Siemens SINAMICS G115D Operating Instructions Manual page 389

Note
When starting / before switching on, use the appropriate circuit to ensure that the motor
brake is released.
Note
With a brake motor:
After maintenance work, 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 data on the rating plate with the operating conditions.
• Check the direction of rotation.
• For a Y / Δ start, a switch is made from star to delta when the starting current of the Y
stage has decayed.
• Check that the electrical connections are securely fastened.
• 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 intake openings and cooling surfaces are clean.
• Check the clearances from the geared motor to adjacent components, see Installation
conditions for the motor (Page 376).
• Establish suitable connections for grounding and equipotential bonding.
• Properly mount and fasten 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.
• Close and seal the terminal box cover and seal the cable entries.
