If a fault occurs in the rectifier unit the fault message is output via the
contacts of the signaling relay and the main contactor is de-energized.
At the same time the red LED lights up on the front panel.
In the event of a fault, the contact is open.
The possible causes for a fault are described under the "Displays,
messages" section.

As long as the pulse disable is set, either there is a fault or the unit is
still pre-charging.
The contact is therefore open.
Inverter pulse disable is canceled as soon as the unit switches to the
"RUN" state.
