WARNING
Electric shock and danger to life due to other energy sources
Touching live components can result in death or severe injury.
• Only work on electrical devices when you are qualified for this job.
• Always observe the country-specific safety rules.
Generally, the following six steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be affected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time specified on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any
of the power connections and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water. Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness in the inverse
sequence.
WARNING
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may

NOTICE
Risk of overheating if external ventilation/cooling is inadequate
If the external fan fails or the motor is operated for a short time without forced ventilation,
this can cause it to overheat. Overheating can cause failures and shorten the service life of
devices/systems.
• Always operate the motor together with an external fan.
Cooling is achieved using a separate ventilation module equipped with a fan that operates
independently of the motor.
The external fan is suitable for use in hazardous zones 2 and 22.
● See also the operating instructions for the explosion-protected external fan in the
appendix.
● Position the motors so that the cooling air can freely flow in and out.
● Maintain the minimum clearance s between the air intake and discharge openings and
adjacent components according to the "Minimum clearance s" diagram.
Steps must be taken to ensure that hot discharged air cannot be drawn back into the
system.
● After screwing the motor tight, refit the removed covers for the foot mounting to the motor
(position 1 in the "Minimum clearance s" diagram). The arrow must point upwards.

Balancing
The rotors are balanced dynamically. The motors are equipped with a smooth shaft as
standard. Observe the following information when balancing shaft ends with feather keys:
● "H" means half feather key = balancing with a half feather key
● "F" means fullkey = balancing with a whole feather key
Attaching the output elements
● Make sure that the balancing method of the output element is correct! The output
elements must be balanced to balance quality grade G2.5 to ISO 1940. Rotary forces that
exceed this are not permissible. Note that rotary forces can also occur with coupling
output.
● If the output element is shorter than the feather key with balancing method "H", the
section of the feather key that protrudes from the shaft contour and output element must
be removed to maintain the balance quality.
● Fit/remove the output elements only by means of suitable equipment:
– Use the threaded hole in the shaft extension (front).
– If necessary, heat up the output element.
– When removing output elements, use a washer to maintain the centering in the shaft
extension.

Safety instructions for commissioning
WARNING
Danger to life as a result of hazardous voltages when connected to inadequately grounded
line supplies
In the case of a fault, connecting a motor to an inadequately grounded line supply can
result in death, severe injury and/or motor damage.
•Connect motors, as part of the drive system, to TN and TT line supplies with grounded
neutral point or to IT line supplies.
•Verify that the SINAMICS devices and motors are compatible with the residual current
device according to EN 61800-5-1 before you connect the devices and motors to the
line supply using residual current devices (RCDs).
•For line supplies with grounded line conductor, e.g. TT line supplies, use an isolating
transformer with grounded neutral point (on the secondary side) between the line supply
and the drive system, so that the motor insulation is not overstressed.
•When connected to IT line supplies, a monitoring device must signal the first fault
between an active part and ground. Remove this fault immediately.
WARNING
Danger to life when the insulation is damaged as a result of the high-voltage test
The motor insulation can be damaged when a motor high voltage test is carried out. You
can get an electric shock when touching live components. Further, electronic components
can be destroyed. The components involved include temperature sensors and encoders,
for example.
•Do not carry out a high-voltage test on the motor.
WARNING
Danger to life when the cooling system bursts
The motor will overheat if it is operated without cooling. When cooling water enters the hot
motor, this immediately and suddenly generates hot steam that escapes under high
pressure. This can cause the cooling water system to burst, resulting in death, severe injury
and material damage.
•Never operate the motor without cooling.
•Only commission the cooling water circuit when the motor is in a cool condition.

68 Operating Instructions, 11/2018, A5E44794151B AA
6.3
Checking the insulation resistance
After long storage or shutdown periods, the insulation resistance of the windings must be
measured to ground with direct voltage.
WARNING
Danger to life through electric shock
During and immediately after the measurement, the terminals are in some cases at
hazardous voltages, which can lead to death when touched.
• Only check the insulation resistance if you are appropriately qualified to do this.
• Before measuring the insulation resistance, read the manual for the insulation
resistance meter you are going to use.
• Never touch the terminals when making measurements or immediately after the
measurement.
• Check the connected supply feeder cables to ensure that the line supply voltage cannot
be connected.
● Always measure the insulation resistance of the winding to the motor enclosure when the
winding temperature is between 20°C and 30°C.
● When performing the measurement, wait until the final resistance value is reached (this
takes approx. one minute).
Limits
The table below specifies the measuring circuit voltage as well as the limit values for the
minimum insulation resistance and the critical insulation resistance with a rated motor
voltage of
U

Note the following:
● Dry, new windings have an insulation resistance of between 100 MΩ and 2000 MΩ
(sometimes higher).
If the insulation resistance is close to the minimum value, this could be due to humidity
and/or an accumulation of dirt.
● The insulation resistance of the motor winding can drop during the course of its service
life can drop due to ambient and operational influences. The critical insulation resistance
for a temperature of 25 °C on the winding can be calculated by multiplying the rated
voltage (kV) by the specific critical resistance value (0.5 MΩ/kV);
Example: Critical resistance for a rated voltage (
V
N) of 0.6 kV:
0.6 kV x 0.5 MΩ/kV = 0.3 MΩ

Note
Cleaning and/or drying the windings when reaching critical insulation resistance
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 evaluated accurately when m
easured on
a winding that has been cooled down to room temperature (approx. 20°C to 30°C).
Note
Measured value close to critical value
If the measured value is close to the critical value, the insulation resistance should be
subsequently checked at su

Recycling and disposal
For environmentally-friendly recycling and disposal of your old device, please contact a
company certified for the disposal of waste electrical and electronic equipment, and dispose
of the old device as prescribed in the respective country of use.
Components
Sort the components for recycling according to whether they are:
●Electronics waste, e.g. sensor electronics
●Iron to be recycled
●Aluminum
●Non-ferrous metal, e.g. motor windings
●Insulating materials
Process materials and chemicals
Sort the process materials and chemicals for recycling according to whether they are:
●Oil
Dispose of the spent oil as special waste in accordance with the spent oil ordinance.
●Grease
●Solvents
●Cleaner solvent
●Paint residues
Do not mix solvents, cleaner solvents and paint residues.
Insulating materials
Electrical insulation materials are mainly used in the stator. Some supplementary
components are made of similar materials and must, therefore, be handled in the same
manner. The insulating materials in question are used on the following items of equipment:
●Various insulators which are used in terminals boxes
●Voltage and current transformers
●Power lines
●Instrument wiring

●Surge arrester
●Capacitors
Disposing of permanent magnets
Permanent magnets must be demagnetized prior to disposal. This helps avoid potential
hazards caused by permanent magnets during and after disposal. Permanent magnets are
heated to demagnetize them.
Permanent magnets can be demagnetized in one of the following ways:
●Arrange for the entire machine to be subject to thermal treatment by a specialist disposal
company.
●Return the machine to the manufacturer who can then remove and demagnetize the rotor
and/or permanent magnets. Rotors that are still installed and have not been
demagnetized must not be transported.
Note
Removing the rotor
The rotor in a machine containing permanent magnets must only be removed by the
manufacturer. Contact the Siemens Service Center.
