Chapter 10 - Troubleshooting and maintenance
Hazardous voltages!
When maintenance on the drive is carried out that includes the removal of
phase modules, the connection of grounding equipment at the appropriate
locations is a must. The grounding equipment ensures that hazardous
voltages cannot be fed into the drive from the main power supply or from
the motor.
When working on the drive, ensure that foreign matter cannot enter the
cabinet. Close the doors and cover openings completely when work is
discontinued. Any foreign matter which accidentally dropped into the
cabinet must be retrieved. Metallic dust, in particular, could cause
malfunction and damage when the drive is energized.
