Each module has a dedicated DC switch-disconnector. When the switch-disconnector
is open, the door to that particular compartment can be opened. It is also allowable
to replace the module, its cooling fan, or its DC fuses.
The motor (output) connections for each module are located at the lower part of the
cubicle; depending on the power of the inverter module, these are either detachable
or non-detachable terminal blocks.
The cubicle is equipped with cable entries for the motor cables in the floor.
