23.11 Opening the circuit-breaker manually
Opening the circuit-breaker manually is carried out by pushing a rod through an actuating opening in the
high-voltage door, thereby operating the OFF pushbutton underneath the high-voltage door. This can be
done with the control door either open or closed. When the control door is closed, the push rod is inserted
through an opening in the control door (1). The indicator for the circuit-breaker position can be seen through
an inspection window (2).

NOTICE
Conflicting operation
The requirement of setting the panel to either local or remote control prevents
operating the panel locally and centrally at the same time.
For any local operations ─ manual or electrical ─ set the panel to local
control, for example by switching the local-remote switch to LOCAL
position.
