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.
INFORMATION
Electrical racking is only possible when both the high-voltage door and the control
door are closed.
After releasing electrical access to the withdrawable circuit-breaker /
circuit-breaker truck, close the control door and padlock it.
