6.5.1
Manually unlocking power-unit doors
To ensure operator protection, the drive is equipped with an electromechanical door
interlocking system. The doors cannot be opened until the make-proof grounding switch has
been closed. In the event of a complete voltage failure including failure of the auxiliary voltage,
the doors cannot be released via the grounding switch.
Because the drive is not yet connected, the doors are locked electromechanically. In order to
facilitate assembly and installation of the drive, the doors can be opened manually.

DANGER
Danger to life as a result of insufficient grounding
The drive must be grounded to ensure that it operates safely and reliably. If the drive is
operated with insufficient grounding, then the protection and monitoring functions can fail.
Death, serious injury, or material damage will result.
● To ensure the correct functioning of the protection and monitoring equipment, ground the
device.
Each cabinet has a grounding lug for grounding the components installed in the cabinet. It is
located at the bottom of the cabinet. Connect the cabinets securely to the plant grounding
system via these grounding lugs.
