DANGER
Hazardous voltages!
Before starting to work on the drive, make sure that:
• the main and auxiliary power supply to the drive is switched off,
locked out, and tagged out,
• the drive is dead,
• safety ground connections are in place,
• personal protective equipment is provided and used when required,
• everyone involved is informed.
Before energizing the drive again, make sure that:
• all foreign objects are removed from the drive,
• all internal and external covers are securely fastened and all doors
are closed, locked and / or bolted,
• the manual release of the safety switches is in the locked position.
DANGER
Hazardous voltages!
When a phase cell is removed from the cabinet, the grounding path
between grounding switch and PE ground busbar is interrupted.
For this reason, connect grounding equipment at the appropriate
locations. The grounding equipment ensures that hazardous voltages
cannot be fed into the drive from the main power supply or the motor.
