Chapter 8. Accessory Maintenance
38
This section describes the removal, replacement, and
adjustment of the various accessories available with
EntelliGuard breakers.
Before any of the operations in this chapter can be per-
formed, the breaker must be removed from its compart-
ment, as described in Section 5.2, and placed on a suitable
work surface.
8.1 Bell Alarm with Lockout
The Bell Alarm with Lockout locks out the breaker in the
event of a protection trip. The device has one normally
open output switch and a trip circuit that are connected to
the secondary disconnect as illustrated in Figure 43. The
switch output provides status feedback to the EntelliGuard
Messenger. The Bell Alarm with Lockout can only be reset
manually by pressing the yellow target/RESET button on
the breaker escutcheon.
Renewal parts for the Bell Alarm with Lockout are a
complete kit including mounting hardware, illustrated in
Figure 44, or the module only.
Removing the Bell Alarm with Lockout
Use the following procedure to remove the Bell Alarm
with Lockout module and mounting plate, as illustrated in
Figure 45. If only the Bell Alarm module is to be replaced,
it is not necessary to remove the mounting plate (perform
steps 1–3 only).
1. Remove the breaker escutcheon, as described in
Section 7.5.
2. Remove the four Bell Alarm wires from the
secondary disconnect, as listed in Table 6. Cut the
wire ties securing the wire bundle to the breaker
frame so that the four wires can be removed with
the Bell Alarm.
3. Remove the two screws and bushings securing the
Bell Alarm module to the mounting plate and
remove the module.
4. Remove the three nuts and lock washers securing
the mounting plate to the breaker frame.
5. Disengage the mounting plate from the breaker
mechanism and remove the plate.
