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. 
 
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 
the TEST position.  This will release the door 
interlock mechanism and the door can now be 
opened. 
Door Interlock Defeat Mechanism: To open the door 
in an emergency, remove two screws.
