Panels with motor operating mechanism control
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.
For any central operations set the panel to remote control.
NOTICE
Covered control elements
For safety reasons, some of the control elements on the high-voltage door are
covered by the control door.
If required, open the control door to uncover the control elements on the
high-voltage door.
INFORMATION
Blocking any racking operation is the precondition for opening the high-voltage
door.
Before opening the high-voltage door, set the access mode indicator to
"T".
