Remove Contactor Cart
To replace the fuses, the contactor cart must be removed from the cabinet.
Below the contactor cart door are two pin holes that receive the pins on the
service cart.
1. Align the service cart with the enclosure, ensuring the contactor cart
platform is the same elevation as the service cart rails.
2. Move the service cart to the cabinet, and insert the cart pins into the
enclosure ( Figure 18 ).

3. Insert cart latch key into the cart latch disengagement and turn the key
approximately a quarter turn clockwise ( Figure 19 ).
Ensure latch is disengaged from the rail.
ATTENTION: A locking key on the front of the cart must be engaged to
ensure the service cart does not roll when removing the contactor cart.
