The gear is manufactured from high-quality bronze. The gearbox is lubricated for life with high-quality synthetic oil. The motor complies with the following regulations: Table 2-1 Overview of the standards Topic Standard Dimensions and operation characteristics EN 60034-1 Degree of protection EN 60034-5 Cooling EN 60034-6 Mounting position according to modular system EN 60034-7 Terminal marking and direction of rotation EN 60034-8 Noise emission EN 60034-9 Thermal protection EN 60034-11 Starting characteristics for rotating electrical motors EN 60034-12 Vibration severity levels EN 60034-14 IEC standard voltages IEC 60038 Safety of machinery EN 60204-1 The motor is equipped with grease-lubricated roller bearings. The bearings are permanently lubricated. In the standard version, the rotor corresponds to vibration severity level A. The technical data for the optional monitoring equipment can be viewed in the circuit diagrams, on the rating plate or in the special order documents. The stator housing and bearing shields are made of die-cast aluminum or cast iron. The surface of the stator housing is equipped with cooling fins and a mounted terminal box or motor connector. 2.2 Shaft seals The shaft sealing rings on the output side prevent lubricant from escaping from the housing at the shaft outlet and prevent pollution from entering the housing. The optimum use of the seals depends on the ambient conditions and the lubricant being used. Radial shaft sealing ring A high-quality radial shaft sealing ring is used as standard seal. The ring is provided with an additional dust lip to protect against contaminants from outside. Permitted oil sump temperatures from -40 C to +80 C. KA 2032 A5E39968267A/RS-AE, 11/2018 5 High temperature-resistant seal (optional) Radial shaft seals made from a temperature-resistant material are used and are able to tolerate higher temperatures. Permitted oil sump temperatures from -25 C to +110 C. 2.3 Cooling NOTICE Dust deposits prevent heat radiation. Dust deposits prevent heat radiation and cause a high housing temperature. Keep the geared motor free from dirt, dust, etc. The gearbox does not normally require additional cooling. The generously dimensioned housing surface is sufficient for dissipating heat losses where there is free convection. If the housing temperature exceeds a value of +80 C, please contact Technical Support. The motor is designed to be cooled by means of fins. An external fan draws in the cooling air through the aperture in the fan cover and blows the air over the surface of the stator housing. 2.4 Rating plate The rating plate on the gearbox or geared motor is made of coated aluminum foil. The rating plate is glued using a special masking film. The film ensures permanent resistance to UV radiation and media of all kinds, such as oils, greases, salt water and cleaning agents. 2.5 Surface treatment 2.5.1 General information on surface treatment Standard-version gearboxes or geared motors are not painted at the factory. If necessary, they can be painted with any kind of commercially available paint. ATEX version gearboxes As standard, the gearbox is not painted. The gearbox is optionally delivered complete with primer and paint finish. ATEX version gearboxes When applying conductive paint, the operating company must ensure that the paint remains in a perfect state. The paint finish must be checked at intervals of approximately 2 - 3 years. ATEX version gearboxes An excessively high electrostatic charge must be avoided. Ensure that highly active mechanisms that cause the paint finish to generate a charge are avoided. Highly active mechanisms that can generate charges: 6 * Fast air with high dust content directed past the gearbox * Sudden escape of compressed gases that contain particles * Harsh abrasive processes (this does not mean manual cleaning / wiping with cleaning cloths) KA 2032 A5E39968267A/RS-AE, 11/2018 WARNING Danger due to electrostatic discharge For paint finishes in explosion group III, the paint can be electrostatically charged as a result of intensive dust turbulence or processes with high levels of electrostatic charging. Risk of explosion as a result of processes with high levels of electrostatic charging Minimize the risk of electrostatic charging by applying effective measures according to IEC 60079-32-1. NOTICE Failure of the external protection Do not damage the paint finish. NOTICE Destruction of the seals Sealing lips must not come into contact with paint. Cover the shaft sealing rings.

Please note that the motor degree of protection is only obtained after correctly connecting up and tightening the cable glands and blanking plugs. KA 2032 A5E39968267A/RS-AE, 11/2018 19 4.11.3 Terminal marking For terminal designations, the following principle definitions apply to three-phase motors: Table 4-2 1 U Terminal designations using the example 1U1-1 1 - 1 x Designation Index showing the pole assignment for pole-changing three-phase motors (lower number = lower speed) or, in special cases, for a subdivided winding x Phase designation (U, V, W) x Index showing winding start (1) Index showing winding end (2) Additional indexes if there is more than one connection per winding x 4.11.4 Additional indices if it is obligatory to connect parallel line feeder cables to several terminals with otherwise identical designations Direction of rotation The motors are suitable for clockwise and counter-clockwise rotation. When the line feeder cables are connected in the phase sequence L1, L2, L3 to U, V, W, the motor rotates clockwise when looking at the drive end of the shaft extension (DE). If two of the connections are swapped, the resulting direction of rotation is counter-clockwise, e.g. L1, L2, L3 to V, U, W. In the case of geared motors intended for only one direction of rotation, e.g. with backstop, the prescribed direction of rotation is marked by a direction arrow on the geared motor. Table 4-3 Direction of rotation of the geared motor with a view of the output shaft Gearbox type NO View of DE of the output shaft NDE of the output shaft 4.11.5 Direction of rotation Output shaft Input shaft Right Left Right Connecting the cables in the terminal box Note Direct contact between the cable lug surfaces and the contact nuts ensures that the connection can carry current. In the case of terminals with terminal clamps, distribute the conductors in such a way that the clamping heights are about the same on both sides of the fillet. This method of connection requires a single conductor to be bent into a U shape or connected with a cable lug. The same applies to the inner and outer terminals of the ground conductor. Select the cable lug size according to the required cable cross-section and stud size. A sloped / angular arrangement is permitted if the required clearances and creepage distances are maintained. Remove the insulation from the conductor ends so that the remaining insulation is almost long enough to reach the cable lug. 4.11.6 External grounding Ensure the following when making connections: The connecting surface must be bare. Protect the surface against corrosion with a suitable substance, e.g. acid-free Vaseline. Insert the cable lug between the contact bracket and the grounding bracket. Do not remove the contact bracket which is pressed into the housing. 20 KA 2032 A5E39968267A/RS-AE, 11/2018 Place the spring washer under the screw head.

Reduce the maximum motor voltage to noncritical values by using an output filter on the converter. The table below shows a comparison between the maximum admissible peak-peak voltage at the motor terminal as stipulated by DIN EN 60034-18-41 and the peak-peak voltage tolerance of SIMOTICS insulation systems.

Other insulation systems on request. 22 KA 2032 A5E39968267A/RS-AE, 11/2018 The following applies for the voltage rise time: Ta > 0.3 0.2 s. The voltages specified are peak-peak values (Vpk/pk). Bearing currents Additional bearing currents due to steep voltage edges when switching. Without output filters, significant voltage variations can occur at the winding terminals. Make sure the drive system is installed in accordance with EMC requirements. Mechanical stress and grease lifetime High speeds that exceed the rated speed and the resulting increased vibrations alter the mechanical running smoothness and the bearings are subjected to increased stress. This reduces the service life of the grease and bearings. Optional add-on units Connect the temperature sensor of the monitoring system and the anti-condensation heating according to the appropriate circuit diagram. Only switch on the anti-condensation heating after the motor has been switched off. 5 Commissioning 5.1 General information for commissioning WARNING Unintentional starting of the drive unit Secure the drive unit to prevent it from being started up unintentionally. Attach a warning notice to the start switch. WARNING Risk of slipping on oil Remove any oil spillage immediately with an oil-binding agent in compliance with environmental requirements. WARNING Hazardous voltage and rotating parts Before starting commissioning, mount the covers required for the correct air guidance. Avoid contact with active, live or rotating parts. 5.2 Checking the insulation resistance Only qualified personnel may work on power installations. WARNING Hazardous voltage at the terminals In some cases, the terminals can be at hazardous voltage levels during the measurement and immediately afterwards. The terminals must not be touched. Carry out a check on the power cables connected to ensure that no voltage can be applied. Note The insulation resistance must be checked before commissioning and after lengthy periods of storage or non-use. Before you begin measuring the insulation resistance, please read the operating manual for the insulation resistance meter you are going to use. Before measuring the insulation resistance, disconnect any main circuit cables that are connected to the terminals. KA 2032 A5E39968267A/RS-AE, 11/2018 23 Note If the critical insulation resistance is less than or equal to this value, the windings must be dried or, if the fan is removed, cleaned thoroughly and dried. Note that the insulation resistance of dried, clean windings is lower than that of warm windings. The insulation resistance can only be properly assessed after conversion to the reference temperature of +25 C. If the measured value is close to the critical value, you must check the insulation resistance at suitably frequent intervals. Measure the minimum insulation resistance of the winding to the motor housing at a winding temperature between +20 C and +30 C. Other insulation resistance values apply to temperatures outside this range. When making the measurement, wait until the final resistance value is reached, approx. 1 minute. Measure the critical insulation resistance at the operating temperature of the winding. Limit values The following limit values are valid for the insulation resistance at a rated voltage of UN < 2 kV and a winding temperature of +25 C. 500 V Measurement voltage 10 M Minimum insulation resistance for new, cleaned or repaired windings 0.5 M/kV Critical specific insulation resistance after a long operating time Note the following: If you measure a winding temperature other than +25 C, convert the measured value to the reference temperature +25 C. The insulation resistance is halved for every 10 K increase in temperature, and it is doubled for every 10 K decrease in temperature. If the insulation resistance is close to or below the minimum value, the cause could be humidity and dirt accumulation. Dry the windings. During operation, the insulation resistance of the windings can fall to the critical insulation resistance due to ambient and operational influences. To calculate the critical insulation resistance value for a winding temperature of +25 C, multiply the rated voltage kV by the specific critical resistance value (0.5 M/kV). Example: Rated voltage UN 690 V: 690 V x 0.5 M/kV = 0.345 M. 5.3 Checking the motor Note Protect the motor against overload. Do not exceed or undershoot limit speeds, e.g during operation with a backstop. Note With a brake motor: Before commissioning, check the constancy of the rated air gap of the brake. The brake motor must be current-free. Check the gap between the armature disk and the solenoid at 3 points with a feeler gauge. Note Additional tests are also required, depending on the particular plant-specific situation. After checking and ensuring the following items, you can start commissioning the motor: Compare the details on the rating plate with the operating conditions. Compare the voltage and frequency of the motor with the line supply values. Check the direction of rotation. A Y / start is switched from star to delta when the starting current of the star stage has decayed. Check that the electrical connections are fixed securely. 24 KA 2032 A5E39968267A/RS-AE, 11/2018 Check all the touch protection measures for both moving and live parts. Check that the monitoring instruments are connected and set correctly. Check the coolant temperature. Check any supplementary equipment being used. Check that air inlet ports and cooling surfaces are clean. Create the appropriate connections for grounding and equipotential bonding. Properly mount and fix the motor. Check that the ventilation is not impeded and that the discharged air - including that from adjacent units - cannot be drawn back in. Check the belt tension if a belt drive is being used. Seal the terminal box cover and seal the cable entries. 5.4 Commissioning a geared motor After mounting, the geared motor is ready for use. Procedure 1. Run the geared motor for a short period of time under no-load operation. 2. Check for any irregularities such as oil leakages, strong vibration and noise. 3. Switch in the load. 4. Allow the geared motor to run. The running-in process should take approximately 24 hours of operation at full load. In most cases, the catalog values will then be reached. You have now started up the geared motor. 6 Operation ATEX version gearboxes The difference between the temperature of the housing and the ambient temperature of max. +40 C must not exceed 70 K. Using a suitable temperature sensor, measure the temperature at the lowest point of the housing (oil sump) or at the mounting surface in the case of output units. We recommend that you monitor the gearbox temperature indirectly by monitoring the motor current. Changes are an indication of possible incipient damage. CAUTION Malfunctions can cause injuries or gearbox damage In the event of changes during operation, the drive unit must be switched off immediately. Determine the cause of the fault using the fault table. Remedy faults or have faults remedied. Check the gearbox or the geared motor during operation for: Excessive operating temperature Changes in gear noise Possible oil leakage at the housing and shaft seals KA 2032 A5E39968267A/RS-AE, 11/2018 25 7 Faults, causes and remedies Note Faults and malfunctions that occur during the warranty period and requiring repair work on the gearbox must be remedied only by Technical Support. If faults occur without a clearly identifiable cause, Siemens AG recommends the services of the Technical Support even after the warranty period has elapsed. If you need the help from the Technical Support, please have the following information ready: * Rating plate data * Nature and extent of the fault * Suspected cause 8 Service and maintenance 8.1 General notes about maintenance work ATEX version gearboxes All measures, checks, and their results must be documented by the operator and records kept in a safe place for 10 years.

Notes This does not represent a fault; frequently, in the course of operation, the sealing ring dries off. During the running-in phase, the shaft sealing ring beds into the shaft. A visible track can be seen on the shaft. Optimum preconditions for a perfect seal are obtained after the running-in phase. Cleaning a geared motor NOTICE Dust deposits cause higher housing temperatures Dust deposits prevent heat radiation. Keep the geared motor free from dirt and dust. NOTICE Cleaning with a high-pressure cleaning appliance Water can penetrate into the geared motor. Seals can become damaged. Do not use a high-pressure cleaning appliance to clean the geared motor. Do not use tools with sharp edges. Switch off the power supply to the drive unit before cleaning it.

Check the gearbox in accordance with the criteria set out in General information (Page 2). Touch up damaged paintwork carefully. 8.6 Servicing the brake 8.6.1 Wear of the spring-operated brake The friction lining and the mechanical components of the brake are subject to wear due to their inherent function. For safe and fault-free operation, the brake must be regularly checked and adjusted, and if necessary, replaced. 8.6.2 Maintenance intervals for the brake For safe and trouble-free operation, check and maintain the spring-operated brake at regular intervals. For operational braking, the maintenance intervals depend on the loading on the brake in the application. Take all causes of wear into account when calculating the maintenance intervals. Siemens AG recommends a regular inspection at fixed time intervals for low loaded brakes, e.g. holding brakes with an emergency stop. Failure to maintain the brake can lead to operating faults, production outage or damage to the plant. Specify a maintenance plan for each application that is appropriate to the operating conditions and loading of the brake. The maintenance intervals and maintenance work for the pneumatic brake are listed in the table. 28 KA 2032 A5E39968267A/RS-AE, 11/2018 Table 8-4 Maintenance interval for the brake Brake Maintenance interval Operational brake According to service life calculation Otherwise every six months After 4 000 operating hours at the latest Holding brake with emergency stop Minimum every 2 years After 1 million cycles at the latest Shorter intervals for frequent emergency stops 8.6.3 Adjusting the air gap WARNING Unintentional starting of the drive unit Switch off the power supply to the drive unit.
