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.
