20 Safety instructions
Note:
•
You can use power cable shields as grounding conductors only when their conductivity
is sufficient.
•
As the normal touch current of the drive is higher than 3.5 mA AC or 10 mA DC, you
must use a fixed protective earth connection. See standard IEC/EN 61800-5-1, 4.3.5.5.2.
Additional instructions for permanent magnet motor drives
￭
Safety in installation, start-up, 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 drive and do the steps in section
•
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.
•
Install temporary grounding to the drive output terminals (U2, V2, W2). Connect the
output terminals together as well as to the PE.
During the start up:
•
Make sure that the motor cannot run overspeed, e.g. driven by the load. Motor overspeed
causes overvoltage that can damage or destroy the capacitors in the intermediate circuit
of the drive.

Safety in operation
WARNING!
Make sure that the motor cannot run overspeed, e.g. driven by the load. Motor
overspeed causes overvoltage that can damage or destroy the capacitors in the
intermediate circuit of the drive.
