4.11 Removal

Removal from the DISCONNECTED posi-
tion with a lift truck.

1.  Open the breaker compartment door.

2.  For ADVAC breakers perform a manual

close and open operation to discharge
the stored energy. Note: if equipped with
UV you must disable the UV prior to
discharging the breaker.

3.  Align the locking tabs of the lift truck with

the lift truck holding slots in the front of
the frame.  Push the lift truck to the
frame to engage the locking tabs with
the compartment.  Lower the truck
platform slightly to lock in place.  The
truck platform should be horizontal and
aligned with the rails in the
compartment.  Set the lift truck foot
brake.  Try pulling the lift truck away from
the frame.  The locking tabs should be
set firmly in place and the brake set.

4. Release the circuit breaker from the

compartment by pulling the interlock
release handles toward the center of the
unit.

5.  Pull the drawout unit straight onto the lift

truck platform. Keep the unit level as
possible.

6.  Align the breaker interlock tabs with the

lift truck slots.  Engage the breaker
interlock tabs by returning the handles to
their outward position.

7.  Verify that the handles are fully outward

and the breaker interlock tabs are in the
lift truck slots.

 WARNING

Do not attempt to remove the breaker
from the circuit breaker compartment
without the required ramp, dolly or lift
truck
