Doors with release lever
(advance and SafeGear)
Breaker doors have a position release lever
assembly on the front of the door (Figures 32 & 33).
This lever actuates by lifting the racking pin in the
withdrawable truck to allow the racking screw to
rotate. The mounting hardware that mounts this
lever in place can be used to also mount
SmartRack™ MV mounting adapter plate. The
exploded view (Figure 33) should be used as a
reference for disassembly and for reassembly of
these parts.
First, the position release lever should be removed
from the switchgear door (Figure 34). There is one
screw, a flat washer and a lock washer that need to
be removed from the center of the lever itself. Then
there are two screws that hold the position release
stop onto the door. Both the position release stop
and position release lever need to be removed and
discarded.
