GE Industrial Solutions Record Plus Cable Operating Mechanism: FC100, FE250 - Manual (Page 6)

5. Attach the drive arm mechanism to the handle
drive link with the connecting pin [11]. Secure
with a retaining ring [12], as shown in Figure 8.
6. Attach one end of the handle-return spring [13]
to the holes in the drive link and the drive arm
extension. Attach the other end to the hole in
the lower flange of the cable adapter assembly.
7. Drill and tap two #8-32 holes in the door, as
shown in Figure 5 and Figure 8. Attach the
interlock bracket [14] to the door with two #8-32
SEMS screws [10] from inside the door.
Alternatively, the bracket may be welded to the
cover, using the dimensions noted with an
asterisk in Figure 8, to locate the upper left
corner of the bracket.
8. Attach the interlock hook [15] to the interlock
bracket [14] with two #8-32 SEMS screws [10].
Use the lower set of holes in the hook for a door
with a 3/4" turned edge (as shown) or the upper
set of holes if the door has a 11/8" turned edge.
9. With the handle in the OFF position, attempt to
close the door. If the interlock blade interferes
with the interlock hook DO NOT force the door
closed. Loosen the two #8-32 screws [10] and
move the interlock hook upward. The door
should close without interference. Try to turn the
handle ON; if the handle turns ON, loosen the
two #8-32 screws [10], secure the interlock hook,
and move the hook toward the bottom of the
enclosure to provide more depression of the
interlock blade, thus preventing the handle from
engaging.
10. As the handle is moved to the ON position, the
interlock hook should engage the interlock
blade, preventing the door from opening unless
the handle interlock is manually disengaged by
rotating the interlock defeat button on the
handle clockwise with a flat-bladed screwdriver
[4]. If the door can be opened with the handle in
the ON position without having to defeat the
interlock blade, readjust the interlock hook
downward and repeat steps 9 and 10.
11. Turn the handle to the OFF position. You should
be able to open the door. Note that if a vault-type
interlock (GE cat. no. TDV1) or a similar
assembly has been installed, the door hardware
must first be defeated.
Step 4 – Install the Cable
Use the following procedure to install one end of the
operating cable to the operating handle, then the
other end to the breaker operating mechanism. This
procedure is illustrated in Figure 9.
1. Slide a 7/16-20 hex nut [17] and lock washer
[18] over the end of the cable with the #10-32 x
7/8" thread. Screw the nut onto the threaded
cable shank past the groove in the middle of the
shank.
2. Screw the cable guide pin [19] onto the same
end of the cable as in step 1. Do not tighten.
3. Place the flange-mounted operating handle [4]
in the OFF position. Position the cable behind
the drive arm linkage, with the groove on the
threaded shank placed into the slot in the
bottom of the cable operator assembly [6].
Tighten the 7/16-20 nut [17] against the cable
operator assembly until it is snug.
4. Insert the cable guide pin [19] on the end of the
cable into the appropriate mounting hole on
the drive arm. Snap the retaining ring [20] into
the groove in the guide pin [19].
5. Slide a 7/16-20 hex nut [17] and lock washer
[18] over the end of the cable with the #10-32 x
3" thread. Screw the nut onto the threaded cable
shank past the groove in the middle of the
shank.
6. Screw two #10-32 hex nuts [21] approximately
23/4" onto the end of the cable. Insert the end
of the cable through the upper end of the slider
on the breaker operating mechanism [1].
7. Insert the groove in the threaded cable shank
into the slot on the bottom of the breaker
operating mechanism [1]. Tighten the 7/16-20
hex nut [17] until it is snug.
8. Verify that the power to the circuit breaker is
OFF. Move the cable-operating handle [4] to the
ON position. Move the two #10-32 hex nuts up
on the cable shaft against the slider bracket.
9. Move the cable-operating handle [4] to RESET
the breaker and place the spring [22] over the
cable end at the breaker. Press the slider of
breaker operating mechanism [1] down and
thread the spring retainer [23] over the end of
the cable. Tighten the spring retainer [23] until
the breaker handle is moved to RESRT position.
The installed height of the spring [22] is
17/16".
10. Move the cable-operating handle [4] ON and
then OFF. If the breaker does not turn ON,
then, with the handle in the OFF position,
adjust the #10-32 hex nuts away from the slider
bracket. Move the operating handle [4] to the
ON position, and then repeat the adjustment, as
needed, until the breaker turns ON. Readjust
the spring installed height to 17/16" with the
cable operating handle [4] ON.
