4.1.1 Mechanical operation door open
When the door is open the circuit breaker or contactor
withdrawable unit can be operated directly from the
controls mounted on the front of the unit. For full
information refer to the individual operations and
maintenance manual.
If the control plug is connected then a full functional test of
the unit is possible.
NOTE
The door cannot be opened when the unit is in the
Service position. To open the door make sure the
unit is in the OFF position and it is racked out fully to
