Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 19 Preparing for use 4.5 Transport and storage 4.5 Transport and storage 4.5.1 Reference to chapter Safety instructions When carrying out any work on the machine, observe the general safety instructions (Page 11) and the specifications contained in EN 501101 regarding safe operation of electrical equipment. WARNING Risk of dropping and swinging when transported suspended If you transport the motor suspended from cables or ropes, the cables or ropes can break, e.g. as a result of damage. Further, if not adequately attached, the motor can swing. This can result in death, serious injury, or material damage. Use additional, suitable lifting equipment for transport and during installation. Two cables alone must be able to carry the complete load. Prevent the lifting equipment from sliding by appropriately securing it. WARNING Toppling over or slipping of the motor The motor can slide or topple over if it is not correctly lifted or transported. This can result in death, serious injury, or material damage. Use all the lifting eyes on the machine. When using the lifting eyes on the machine, do not attach any additional loads or weight. The lifting eyes are only designed for the weight of the machine itself. Any eyes that are screwed in must be tightly fastened. Eyebolts must be screwed in right up to their supporting surface. Comply with the permissible eyebolt loads. When necessary, use suitably dimensioned transport equipment, for example hoisting straps (EN1492-1) and load restraints (EN12195-2). 4.5.2 Transporting certain frame sizes Note When lifting the machines for transport, only lift them in a position that corresponds to their basic construction type. 20 Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 Preparing for use 4.5 Transport and storage 4.5.3 Types of construction on the rating plate The type of construction of the machine is stated on the rating plate. 4.5.4 Storage Storing outdoors NOTICE Damage to the motor Damage can occur if incorrectly stored. Take all precautions to protect the motor under extreme climatic conditions, e.g. salt-laden and/or dusty, moist/humid atmospheres. Choose a dry storage location which is safe from flooding and free from vibration. Repair any damage to the packaging before putting the equipment into storage if this is necessary to ensure proper storage conditions. In order to ensure protection against ground moisture, locate machines, equipment and crates on pallets, wooden beams or foundations. Prevent equipment from sinking into the ground. Do not impede air circulation under the stored items. Covers or tarpaulins used to protect the equipment against the weather must not come into contact with the surfaces of the equipment. Use wooden spacer elements to ensure that air can circulate freely around the equipment. Storing indoors The storage rooms must provide protection against extreme weather conditions. They must be dry, free from dust, frost and vibration and well ventilated. Bare metal surfaces For transport, the bare surfaces (shaft ends, flange surfaces, centering edges) should be coated with an anti-corrosion agent which will last for a limited amount of time (<6 months). Apply suitable anti-corrosion measures for longer storage times. Condensation drain hole Open any condensation drain holes to drain the condensation depending on the environmental conditions, every six months at the latest. Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 21 Preparing for use 4.6 Bearing lifetime 4.6 Bearing lifetime Storage temperature Permissible temperature range: -20 C to +50 C Maximum permissible air humidity: 60% For machines that have a special design regarding the coolant temperature in the operating state or the installation altitude, other conditions could apply regarding the storage temperature. In this case, refer to the machine rating plate for data on the coolant temperature and installation altitude. Storage time Turn the shaft once every year to avoid bearing brinelling. Prolonged storage periods reduce the useful life of the bearing grease (aging). Open bearings For open bearings, e.g. 1Z, check the status of the grease when stored for longer than 12 months. Replace the grease if it is identified that the grease has lost its lubricating properties or is polluted. The consistency of the grease will change if condensation is allowed to enter. Closed bearings For closed bearings, replace the DE and NDE bearings after a storage time of 48 months. NOTICE Storage The motor can be damaged if you use it or store it unprotected outdoors. Protect the motor against intensive solar radiation, rain, snow, ice and dust. Use a superstructure or additional cover, for example. If required, contact the Siemens Service Center, or technically coordinate outdoors use. Note If the torque levels are very unequal (e.g. when a reciprocating compressor is being driven), a non-sinusoidal machine current will be induced whose harmonics can have an impermissible effect on the supply system and cause impermissible interference emissions as a result. 22 Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 Preparing for use 4.7 Converter operation Note Converter If operated with a frequency converter, the emitted interference varies in strength, depending on the design of the converter (type, interference suppression measures, manufacturer). Avoid that the specified limit values stipulated for the drive system (consisting of the motor and converter) are exceeded. You must observe the EMC information from the manufacturer of the converter. The most effective method of shielding is to conductively connect a shielded machine supply cable to the metal terminal box of the machine (with a metal screw connection) over a large surface area. On machines with integrated sensors (e.g. PTC thermistors), disturbance voltages caused by the converter may occur on the sensor cable. 4.7 Converter operation 4.7.1 Parameterizing the converter If the design of the motor requires connection to a particular converter type, the rating plate will contain corresponding additional information. Correctly parameterize the converter. Parameterizing data can be taken from the machine rating plate (not the supplementary rating plate with the operating data when connected to a converter). You can find parameter data here: - In the operating instructions for the converter. - In the SIZER engineering tool - In the SINAMICS Configuration Manuals. - For explosion-protected machines, also in the declaration of compliance with the order 2.1. Do not exceed the specified maximum speed limit nmax. You can either find this on the rating plate nmax, on the supplementary plate for converter operation as the highest speed, or in the type-specific catalog. Operate the machine only for a short period at the maximum speed. Operating the machine for an extended period at the maximum speed may cause vibrations with an increased frequency and consequently higher noise levels. Check that the machine is cooled sufficiently for commissioning purposes. Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 23 Preparing for use 4.7 Converter operation 4.7.2 Reducing bearing currents during operation with converter (low voltage) Taking the following actions will reduce the bearing currents: Ensure that the contacts are established over a large area. Solid copper cables are not suitable for high frequency grounding because of the skin effect. Equipotential bonding conductors: Use equipotential bonding conductors: Between motor and driven machine Between motor and converter Between the terminal box and the RF grounding point at the motor enclosure. Selecting and connecting the cable: As far as possible, use symmetrically arranged, shielded connection cables. The cable shielding, made up of as many strands as possible, must have good electrical conductivity. Braided shields made of copper or aluminum are very suitable. The shield is connected at both ends, at the motor and converter. To ensure good discharging of high-frequency currents, provide contacting over a large surface area: - as contact established through 360 at the converter - at the motor, for instance with EMC glands at the cable entries If the cable shield is connected as described, then it ensures the specified equipotential bonding between the motor enclosure and converter. A separate RF equipotential bonding conductor is then not necessary. / / 3( / / / 3( / / / 3( / 3( Concentric copper or aluminum shield Steel armor If the cable shield is not connected due to special secondary conditions, or not adequately connected, then the specified equipotential bonding is not provided. In this particular case, use a separate RF equipotential bonding conductor: - Between the motor enclosure and protective ground rail of the converter. - Between motor enclosure and driven machine - Use braided flat copper straps or high-frequency cables with finely-stranded conductors for the separate RF equipotential bonding cable. Solid copper cables are not suitable for high frequency grounding because of the skin effect. - Ensure that the contacts are established over a large area. 24 Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 Preparing for use 4.7 Converter operation Overall system design To specifically reduce bearing currents, you must consider the system as a whole, which comprises the motor, converter, and driven machine. The following measures support you when reducing bearing currents and help to avoid damage: In the overall system, set up a properly meshed grounding system with low impedance. Use the common-mode filter (damping cores) at the converter output. The Siemens sales representative is responsible for selection and dimensioning. Limit the rise in voltage by using output filters. Output filters dampen the harmonic content in the output voltage. Note Converter documentation The operating instructions for the converter are not part of this documentation. Refer also to the configuration information for the converter. 4.7.3 Insulated bearings when operated with a converter If the machine is operated from a low-voltage converter, insulated bearings are fitted at the NDE and an insulated encoder with insulated bearings (option). Comply with the plates on the machine relating to bearing insulation and possible bridges.

Bearing currents can damage bearings. Also for subsequent installation work, such as the installation of an automatic lubrication system or a non-insulated vibration sensor, make sure that the bearing insulation cannot be bridged. Contact the Service Center, if necessary. Tandem operation If you connect two motors in series in "tandem operation", install an insulated coupling between the motors. Driving machine Motor Coupling Image 4-2 Insulated bearings Insulated tachometer fitting Insulated coupling Schematic representation of a tandem drive NOTICE Bearing damage Bearing currents can flow if the coupling between the motors of the tandem drive is not insulated. This can damage the DE bearings of both motors. Use an insulated coupling to link the motors. 4.7.4 Operation with insulated coupling (EX) If you connect two motors in series in "tandem operation", fit a coupling between the motors; this coupling should satisfy Directive 94/9/EC (up to April 19, 2016, from April 20, 2016 according to directive 2014/34/EU) or the regulations that apply in the country where the equipment is installed. 26 Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 5 Installation 5.1 Reference to chapter Safety instructions When carrying out any work on the machine, observe the general safety instructions (Page 11) and the specifications contained in EN 501101 regarding safe operation of electrical equipment. 5.2 Conformity Note Loss of conformity with European directives In the delivery state, the machine corresponds to the requirements of the European directives. Unauthorized changes or modifications to the machine lead to the loss of conformity with European directives and the loss of warranty. 5.3 Preparing for installation 5.3.1 Requirements for installation The following requirements must be satisfied prior to starting installation work: Staff have access to the operating and installation instructions. The machine is unpacked and ready for mounting at the installation location. Note Measure the insulation resistance of the winding before starting installation work Wherever possible, measure the insulation resistance of the winding before starting installation work. If the insulation resistance lies below the specified value, take appropriate remedial measures. These remedial measures may necessitate the machine being removed again and transported. Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 27 Installation 5.3 Preparing for installation 5.3.2 Safety instructions Note Note also the technical data on the rating plates on the motor enclosure. NOTICE Damage to the motor To avoid material damage, before commissioning, check whether the correct direction of rotation of the machine has been set on the customer side, e.g. by decoupling from the driven load. 5.3.3 Insulation resistance 5.3.3.1 Insulation resistance and polarization index Measuring the insulation resistance and polarization index (PI) provides information on the condition of the machine. It is therefore important to check the insulation resistance and the polarization index at the following times: Before starting up a machine for the first time After an extended period in storage or downtime Within the scope of maintenance work The following information is provided regarding the state of the winding insulation: Is the winding head insulation conductively contaminated? Has the winding insulation absorbed moisture? As such, you can determine whether the machine needs commissioning or any necessary measures such as cleaning and/or drying the winding: Can the machine be put into operation? Must the windings be cleaned or dried? Detailed information on testing and the limit values can be found here: "Testing the insulation resistance and polarization index" (Page 29) 28 Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 Installation 5.3 Preparing for installation 5.3.3.2 Testing the insulation resistance and polarization index WARNING Hazardous voltage at the terminals During and immediately after measuring the insulation resistance or the polarization index (PI) of the stator winding, hazardous voltages may be present at some of the terminals. Contact with these can result in death, serious injury or material damage. If any power cables are connected, check to make sure line supply voltage cannot be delivered. Discharge the winding after measurement until the risk is eliminated, e.g. using the following measures: - Connect the terminals with the ground potential until the recharge voltage drops to a non-hazardous level - Attach the connection cable. Measure the insulation resistance 1. Before you begin measuring the insulation resistance, please read the operating manual for the insulation resistance meter you are going to use. 2. Make sure that no power cables are connected. 3. Measure the winding temperature and the insulation resistance of the winding in relation to the machine enclosure. The winding temperature should not exceed 40 C during the measurement. Convert the measured insulation resistances in accordance with the formula to the reference temperature of 40 C. This thereby ensures that the minimum values specified can be compared. 4. Read out the insulation resistance one minute after applying the measuring voltage. Limit values for the stator winding insulation resistance The following table specifies the measuring voltage and limit values for the insulation resistance. These values correspond to IEEE 432000 recommendations. Table 5-1 Stator winding insulation resistance at 40 C VN [V] VMeas [V] RC [M] U 1000 500 5 1000 U 2500 500 (max. 1000) 100 2500 < U 5000 1000 (max. 2500) 5000 < U 12000 2500 (max. 5000) U > 12000 5000 (max. 10000) Urated = rated voltage, see the rating plate Umeas = DC measuring voltage RC = minimum insulation resistance at reference temperature of 40 C Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 29 Installation 5.3 Preparing for installation Conversion to the reference temperature When measuring with winding temperatures other than 40 C, convert the measuring value to the reference temperature of 40 C according to the following equations from IEEE 43-2000. (1) RC = KT * RT (2) KT = (0.5) (40-T)/10 RC Insulation resistance converted to 40 C reference temperature kT Temperature coefficient according to equation (2) RT Measured insulation resistance for measuring/winding temperature T in C 40 Reference temperature in C 10 Halving/doubling of the insulation resistance with 10 K T Measuring/winding temperature in C In this case, doubling or halving the insulation resistance at a temperature change of 10 K is used as the basis. The insulation resistance halves every time the temperature rises by 10 K. The resistance doubles every time the temperature falls by 10 K. For a winding temperature of approx. 25 C, the minimum insulation resistances are 20 M (U 1000 V) or 300 M (U > 1000 V). The values apply for the complete winding to ground. Twice the minimum values apply to the measurement of individual assemblies. Dry, new windings have an insulation resistance of between 100 and 2000 M, or possibly even higher values. An insulation resistance value close to the minimum value could be due to moisture and/or dirt accumulation. The size of the winding, the rated voltage and other characteristics affect the insulation resistance and may need to be taken into account when determining measures. Over its operating lifetime, the motor winding insulation resistance can drop due to ambient and operational influences. Calculate the critical insulation resistance value depending on the rated voltage by multiplying the rated voltage (kV) by the specific critical resistance value. Convert the value for the current winding temperature at the time of measurement, see above table. Measuring the polarization index 1. To determine the polarization index, measure the insulation resistances after one minute and ten minutes. 2. Express the measured values as a ratio: PI = Rinsul 10 min / Rinsul 1 min Many measuring devices display these values automatically following the measurement. For insulation resistances > 5000 M, the measurement of the PI is no longer meaningful and consequently not included in the assessment. 30 R(10 min) / R(1 min) Assessment 2 Insulation in good condition <2 Dependent on the complete diagnosis of the insulation Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 Installation 5.4 Installation NOTICE Damage to insulation If the critical insulation resistance is reached or undershot, this can damage the insulation and cause voltage flashovers. Contact the Service Center. If the measured value is close to the critical value, you must subsequently check the insulation resistance at shorter intervals. Limit values of the anti-condensation heating insulation resistance The insulation resistance of the anti-condensation heating with respect to the machine housing should not be lower than 1 M when measured at 500 V DC. 5.4 Installation 5.4.1 Machine installation General DANGER Danger caused by falling eyebolts In the event of a fault/fire, increased vibration levels occur that can loosen eye bolts. This will result in severe bodily injury or death. Remove all of the eyebolts after installing the motor in the equipment. For vertical installation, use all of the eyebolts provided and when necessary, hoisting straps (DIN EN 1492-1) and/or lashing straps (DIN EN 12195-2) to stabilize the position of the motor. Prevent foreign bodies from falling into the fan cover. For vertical machine installation with the shaft end facing downwards, attach a protective canopy. If the shaft extension is facing upwards, liquid must be prevented from entering by moving along the shaft. Clean bare metal surfaces with anti-corrosion agent using white spirit to ensure proper installation and / or machine mounting. Do not obstruct ventilation. Do not draw in the discharged air directly - also from adjacent equipment.

Note the following safety information before connecting-up the machine: Only qualified and trained personnel should carry out work on the machine while it is stationary. Disconnect the machine from the power supply and take measures to prevent it being reconnected. This also applies to auxiliary circuits. Check that the machine really is in a no-voltage condition. Establish a safe protective conductor connection before starting any work. If the incoming power supply system displays any deviations from the rated values in terms of voltage, frequency, curve form or symmetry, such deviations will increase the temperature and influence electromagnetic compatibility. Operating the machine on a line supply system with a non-grounded neutral point is only permitted over short time intervals that occur rarely, e.g. the time leading to a fault being eliminated (ground fault of a cable, EN 60034-1). 6.2.1 Direction of rotation The standard motors are suitable for clockwise and counter-clockwise rotation. For defined directions of rotation (direction of rotation arrow), appropriately connect the line power cables. If you connect the line cables with phase sequence L1, L2, L3 at U, V, W or according to NEMA at T1 T2 T3, then the machine rotates in the clockwise direction. If you interchange two connections, e.g. L1, L2, L3 at V, U, W or according to NEMA at T2 T1 T3, then the machine rotates counter-clockwise.

NOTICE Damage to the machine In order to avoid material damage, check the following points before commissioning the motor: Using appropriate measures, check whether the correct direction of rotation of the motor has been set by the customer, e.g. by decoupling from the driven load. Ensure that temperature-sensitive parts (cables, etc.) are not in contact with the machine enclosure. Ensure that the condensation drain holes are always located at the lowest part of the motor. NOTICE Damage caused by insufficient cooling Effective cooling is no longer possible if air guidance of the machine is not provided as intended. This can damage the machine. Before commissioning, attach the covers to guarantee the intended air guidance. Measures Once the system has been correctly installed, you should check the following prior to commissioning: Ensure that the machine has been correctly installed and aligned. Connect the machine corresponding to the specified direction of rotation. Ensure that the operating conditions match the data specified on the rating plate. Lubricate the bearings, depending on the version. Ensure that machines with roller bearings, which have been stored for longer than 24 months, are relubricated. Also observe the notes in Chapter Preparation for use. Ensure that any optional supplementary machine monitoring equipment has been connected correctly and is functioning as it should. For versions with bearing thermometers, check the bearing temperatures when the machine starts to run for the first time. Set the values for alarm and shutdown at the monitoring device. Also observe the notes in Chapter Setting values for monitoring the bearing temperature. Corresponding to the control and speed monitoring functions implemented, ensure that the machine cannot exceed the permissible speeds specified on the rating plate. Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 41 Commissioning 7.2 Measures before start-up Ensure the correct setting conditions of the drive output elements depending on the type (e.g. alignment and balancing of couplings, belt forces in the case of a belt drive, tooth forces and tooth flank backlash/play in the case of gear wheel output, radial and axial clearance in the case of coupled shafts). Comply with the minimum insulation resistances and minimum air clearances. Ensure correct grounding and potential bonding connection of the protective conductor. Tighten all mounting bolts, connection elements and electrical connections to the specified torques. Remove any lifting eyes that were screwed after installation - or secure them to prevent them becoming loose. Rotate the rotor to ensure that it does not touch the stator. Implement all touch protection measures for both moving and live parts. Ensure that free shaft extensions cannot be touched, e.g. by attaching covers. Secure any featherkeys so that they cannot be flung out. Ensure that the optional external fan is ready for operation and connected so that it rotates in the specified direction. Ensure that the cooling airflow is not obstructed or diminished in any way. If an optional brake is being used, ensure that it is functioning perfectly. Comply with the specified mechanical limit speed nmax, and ensure that it is not exceeded. If the design of the machine requires the converter to be assigned in a particular way, the relevant information will be provided on the rating plate or an additional label. Note It may be necessary to perform additional checks and tests in accordance with the specific situation on site. 7.2 Measures before start-up WARNING Rotating parts Electric motors contain dangerous rotating parts. Fatal or severe injuries and substantial material damage can occur if the required covers are removed or if the motors are not handled, operated, or maintained properly. Before commissioning, attach the covers that prevent you inadvertently coming into contact with active and rotating parts. 42 Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 Commissioning 7.2 Measures before start-up NOTICE Damage caused by inadequate cooling Effective cooling is no longer possible if the motor air guidance is implemented as intended. This can damage the motor. Before commissioning, attach the covers in order to guarantee the intended air guidance. Measures Once the system has been correctly installed, you should check the following prior to commissioning: The machine has been assembled and aligned correctly. The machine has been connected so that it rotates in the direction specified. The operating conditions match the data specified on the rating plate. The bearings have been lubricated as appropriate for the version used. Rolling-contact bearing machines which have been in storage for more than 24 months have been relubricated. Any supplementary machine monitoring equipment has been connected correctly and is functioning as it should. For versions with bearing thermometers, the bearing temperatures must be checked during the machine's first period of operation. The warning and shutdown values are set on the monitoring device. Appropriately configured control and speed monitoring functions ensure that the machine cannot exceed the permissible speeds specified on the rating plate. The output elements have the correct settings for their type (e.g. alignment and balancing of couplings, belt forces in the case of a belt drive, tooth forces and tooth face clearance in the case of toothed-wheel power output, radial and axial clearance in the case of coupled shafts). The minimum insulation resistance and minimum clearance values have been adhered to. The grounding and equipotential bonding connections have been established correctly. All fixing screws, connection elements, and electrical connections have been tightened to the specified torques. Remove all eyebolts after the motor has been mounted. The rotor can turn without coming into contact with the stator. All touch protection measures for both moving and live parts have been implemented. In cases where the shaft extension is not being used and is, therefore, exposed, it has been covered and the feather key has been secured to prevent it from being thrown out. If being used, the external fan is ready for operation and connected so that it rotates in the direction specified. The flow of cooling air is not obstructed. Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 43 Commissioning 7.3 Switching on If a brake is being used, it is functioning correctly. The specified mechanical limit speed n max is adhered to. If the design of the machine requires the converter to be assigned in a particular way, the relevant information will be provided on the rating plate or an additional label. Note It may be necessary to perform additional checks and tests in accordance with the specific situation on site. 7.3 Switching on Measures for start-up After installation or inspections, the following measures are recommended for normal start-up of the machines: Start the machine without a load. To do this, close the circuit breaker and do not switch the machine off prematurely. Switching the machine off again while it is starting up and still running at slow speed should be kept to a bare minimum, for example for checking the direction of rotation or for checking in general. Allow the machine to run to a standstill before switching it back on again. Check mechanical operation for noise or vibration at the bearings or end shields. If the machine is not running smoothly or is emitting abnormal noises, switch it off, and determine the cause of the fault as it runs down. If mechanical operation improves immediately after the machine is switched off, then the cause is magnetic or electrical, e.g. voltage imbalance, magnetic imbalance. If mechanical operation does not improve immediately after switching the machine off, then the cause is mechanical, e.g. an imbalance in the electrical machines or in the driven machine, inadequate alignment of the machine set, operation of the machine with the system resonating (system = machine + base frame + foundations etc.). If the machine runs perfectly in terms of its mechanical operation, switch on any cooling devices present and continue to monitor the machine for a while as it idles. If it runs perfectly, connect a load. Check that it runs smoothly. Read off and document the values for voltage, current, and power. Where possible, read off corresponding values for the driven machine and document them as well. Monitor the bearing temperature, winding temperature, etc. until the system reaches a steady state. Document these, provided this is possible with existing measuring instruments. 44 Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 Commissioning 7.3 Switching on Commissioning measures for smoke extraction motors according to EN 12101-3 The procedures laid down in EN 12101-3 must be complied with when testing the motors, installed in the fan unit.

Fatal or serious injuries and substantial material damage can occur if maintenance work is performed on the machine when it is not stopped or not de-energized. Perform maintenance work on the machine only when it is stopped. The only operation permissible while the machine is rotating is regreasing the roller bearings. When performing maintenance work, comply with the five safety rules (Page 11). WARNING Machine damage If the machine is not maintained it can suffer damage. This can cause faults which can result in eventual or immediate death, serious injury or material damage. Perform regular maintenance on the machine. CAUTION Dust disturbances when working with compressed air When cleaning with compressed air, dust, metal chips, or cleaning agents can be whirled up. Injuries can result. When cleaning using compressed air, make sure you use suitable extraction equipment and wear protective equipment (safety goggles, protective suit, etc.). Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 51 Maintenance 9.3 Inspection NOTICE Damage to insulation If metal swarf enters the winding head when cleaning with compressed air, this can damage the insulation. Clearance and creepage distances can be undershot. This may cause damage to the machine extending to total failure. When cleaning with compressed air, ensure there is adequate extraction. NOTICE Machine damage caused by foreign bodies Foreign bodies such as dirt, tools or loose components, such as screws etc., can be left by accident inside the machine after maintenance is performed. These can cause short circuits, reduce the performance of the cooling system or increase noise in operation. They can also damage the machine. When carrying out maintenance work, make sure that no foreign bodies are left in or on the machine. Securely attach all loose parts again once you have completed the maintenance procedures. Carefully remove any dirt. Note Operating conditions and characteristics can vary widely. For this reason, only general intervals for inspection and maintenance measures can be specified here. 9.3 Inspection 9.3.1 General inspection specifications Notes Note Pay particular attention to the relubrication intervals for rolling bearings that deviate from the inspection intervals. Note When servicing a three-phase machine, it is generally not necessary to dismantle it. The machine only has to be dismantled if the bearings are to be replaced. 52 Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 Maintenance 9.4 Maintenance 9.4 Maintenance 9.4.1 Maintenance intervals CAUTION Skin irritations and eye inflammations Many greases can cause skin irritations and eye inflammations. Follow all safety instructions of the manufacturer. The machines are equipped with permanently lubricated roller bearings. A regreasing device is optional. Please note the following in order to identify faults at an early stage, rectify them and avoid follow-on damage: Maintain the machine regularly and carefully. Inspect the machine. Motors must be allocated a revision/inspection number after inspection. Operating situations and characteristics can vary widely. For this reason, only general maintenance intervals are specified here. Maintenance intervals should therefore be scheduled to suit the local conditions (dirt, starting frequency, load, etc.). NOTICE Motor failure Material damage can occur if the machine develops faults or is overloaded. Immediately inspect the machine if faults occur. An immediate inspection is especially necessary, if the three-phase motor is excessively stressed, either electrically or mechanically (e.g. overload or short-circuit). Measures, intervals and deadlines Measures after operating period intervals or deadlines have elapsed: Table 9-1 Operating period intervals Measures Operating period intervals Intervals Initial inspection After 500 operating hours After 1/2 year at the latest Relubrication (optional) See the lubricant plate Clean Depending on the degree of pollution Main inspection Approximately every 16000 operating hours Drain condensate Depending on the climatic conditions Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 After two years at the latest 53 Maintenance 9.4 Maintenance 9.4.2 Re-greasing For machines with regreasing system, relubrication intervals, grease quantity and grease grade are provided on the lubricant plate. Additional data can be taken from the main machine rating plate. Grade of grease for standard motors (IP55) UNIREX N3 - ESSO. Note It is not permissible to mix different types of grease. Prolonged storage periods reduce the useful lifetime of the bearing grease. Check the condition of the grease if the equipment has been in storage for more than 12 months. If the grease is found to have lost oil content or to be contaminated, the machine must be immediately relubricated before commissioning. For information on permanently-greased bearings, please refer to the section titled Bearings (Page 57). Procedure To relubricate the roller bearings, proceed as follows: 1. Clean the grease nipples at the drive end and non-drive end. 2. Press-in the specified grease and amount of grease according to the data stamped on the lubrication plate. - Please observe the information on the rating and lubricant plates. - Regreasing should be carried out when the motor is running (max. 3600 rpm). The bearing temperature can rise significantly at first, and then drops to the normal value again when the excess grease is displaced out of the bearing. NOTICE This invalidates the warranty and operational safety Mixing different types of grease can lead to material damage on the machine. If you use or mix types of grease other than UNIREX N3, this invalidates the warranty and standard conformity with the EN 12101-3 test standard. Only use UNIREX N3 for re-lubrication purposes. 54 Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 Maintenance 9.4 Maintenance 9.4.3 Cleaning Cleaning the grease ducts and spent grease chambers The spent grease collects outside each bearing in the spent grease chamber of the outer bearing cap. When replacing bearings, remove the spent grease. Note Dismantle the bearing cartridges to replace the grease in the lubrication duct. Cleaning the cooling air ducts Regularly clean the cooling air ducts through which the ambient air flows. The frequency of the cleaning intervals depends on the local degree of fouling. NOTICE Damage to the machine Material damage can occur if you direct compressed air in the direction of the shaft outlet or machine openings. Avoid pointing compressed air directly onto shaft sealing rings or labyrinth seals of the machine. 9.4.4 Cleaning machines with cover for the textile industry In the case of machines with fan covers for the textile industry, regularly remove fluff balls, fabric remnants, and similar types of contamination (particularly at the air passage opening between the fan cover and cooling fins of the machine enclosure) to ensure that the cooling air can flow without obstruction.

WARNING Hazardous voltage The winding can be damaged if objects are introduced into the condensation holes (optional). This can lead to death, serious injury or material damage. Note the following to maintain the degree of protection: Switch off the machine so that it is in a no-voltage condition before you open the condensation drain holes. Close the condensation drain holes, e.g. using T-plugs, before commissioning the machine. NOTICE Reduction of the degree of protection If condensation drain holes are not closed, then this can result in material damage to the motor. In order to maintain the degree of protection, after the condensation has been drained, you must close all of the drain holes. 9.5 Repair 9.5.1 Reference to chapter Safety instructions When carrying out any work on the machine, observe the general safety instructions (Page 11) and the specifications contained in EN 501101 regarding safe operation of electrical equipment. 56 Smoke extraction motors Compact Operating Instructions, 03/2016, 56108000040019 Maintenance 9.5 Repair 9.5.2 Safety instructions Safety instructions for smoke extraction motors WARNING Functional endurance when faults/fires occur The insulation system of the machine is exposed to smoke and heat for 2 hours, which it has to withstand. Changes to the winding and cable can result in death, serious injury, or material damage. Only the manufacturer must replace or repair special windings with heat resistant insulation and motor cables. Under no circumstances should other repair workshops carry out this work. The motors can no longer be repaired after a fault event (fire). Replace the motor, even if it still functions. 9.5.3 Bearings 9.5.3.1 Bearings Refer to the rating plate or the catalog for the designations of the bearings being used. Bearing lifetime Prolonged storage periods reduce the useful lifetime of the bearing grease. For permanently lubricated bearings, this reduces the bearing service life. We recommend that the bearings or grease are replaced after a storage time of 12 months; if the time exceeds 4 years, replace the bearings or the grease. Replacing bearings Recommended interval after which bearings are to be replaced under normal operating conditions: Table 9-2 Bearing replacement intervals Ambient temperature Principle of operation Bearing replacement intervals 40 C Horizontal coupling operation 40 000 h 40 C With axial and radial forces 20 000 h Do not reuse bearings that have been removed.
