Safety locking system (option M10)

The safety locking system is based on the key transfer system developed by Castell. It is a
supplementary mechanism to the electromechanical door locking system integrated as
standard. The medium-voltage breaker must be opened before access can be gained to the
coded key of the key exchange unit. The opened medium-voltage breaker releases the key to
the key exchange unit. This key enables the access to the keys for the cabinet doors of the
power unit. This key interlocking system ensures that the converter is disconnected from the
medium-voltage supply and that no cabinet components are connected to medium voltage. As
long as the cabinet doors are not closed again and the keys to the power-unit cabinet are not
inserted back in the key exchange unit, the key for the medium-voltage breaker will not be
released. The medium-voltage breaker cannot be switched on again.
