24 Safety instructions
Additional instructions for permanent magnet motor
drives
Safety in installation, start-up and maintenance
These are additional warnings concerning permanent magnet motor drives. The other
safety instructions in this chapter are also valid.
WARNING!
Obey these instructions. If you ignore them, injury or death and
damage to the equipment can occur.
•
Do not do work on the drive when the permanent magnet motor is rotating. A rotating
permanent magnet motor energizes the drive including its input power terminals.
Before installation, start-up and maintenance work on the drive:
•
Stop the motor.
•
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.
•
Measure that the installation is de-energized.
•
Use a multimeter with an impedance of at least 1 Mohm.
•
Make sure that the voltage between the drive output terminals (U2, V2, W2) and
the grounding (PE) busbar is close to 0 V.
•
Make sure that the voltage between the drive input power terminals (1L1, 1L2,
1L3) and the grounding (PE) busbar is close to 0 V.
•
Make sure that the voltage between the plus and minus busbars of the drive DC
link and the grounding (PE) busbar is close to 0 V.
•
Install temporary grounding to the drive output terminals (U2, V2, W2). Connect the
output terminals together as well as to the PE.
•
Make sure that the operator cannot run the motor over the rated speed. Motor
overspeed causes overvoltage which can damage the capacitors in the intermediate
circuit of the drive.
