Before installation, start-up and maintenance work on the drive:
•
Stop the drive.
•
Disconnect the motor from the drive with a safety switch or by other means.
•
If you cannot disconnect the motor, make sure that the motor cannot rotate during work.
Make sure that no other system, like hydraulic crawling drives, can rotate the motor
directly or through any mechanical connection like felt, nip, rope, etc.
•
Do the steps in section
•
Install temporary grounding to the drive output terminals (T1/U, T2/V, T3/W). Connect
the output terminals together as well as to the PE.
During the start-up:
•
Make sure that the motor cannot run overspeed, for example, driven by the load. Motor
overspeed causes overvoltage that can damage or destroy the capacitors in the
intermediate circuit of the drive.
