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.

Dust protection (option M11)
This option equips the cabinet doors with additional filter mats. The filter mats prevent the entry
of dangerous dust deposits on the power module components.
The filter mats are fitted to the exterior of the cabinet doors, which means that they can be
replaced during operation.
The degree to which the filter mats are contaminated is constantly monitored by a differential
pressure system. A message is output in good time prompting the operator to service the filter
mats before they become blocked.
3.6.31
Power cable connection at the drive input from above (option M13)
You can introduce the line-side power cable into the cabinet from the top.
3.6.32
Signal and control cable (max. 2.5 mm²) (option M32)
Signal and control cables are connected directly to the terminals on Terminal Module TM31 or
TM15 as standard. The maximum connectable cross-section for these cables to the TM31 and
TM15 Terminal Modules is limited to 1.5 mm
With option M32, you can connect signal and control cables with connection cross-sections of
up to 2.5 mm
