Final procedure steps
Next, insert the racking crank for moving the withdrawable
circuit-breaker / circuit-breaker truck.
Racking the withdrawable circuit-breaker / circuit-breaker truck is set to manual operation.
27.5 Selecting electrical operation for racking
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.
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.
