Installing the Bell Alarm with Lockout

Use the following procedure to install the Bell Alarm with

Lockout mounting plate and module. If this is a new

installation into a breaker that was not equipped at the

factory with a Bell Alarm with Lockout, see the installation

instructions in DEH238, supplied with the Bell Alarm with

Lockout kit. If only the module is to be replaced, begin at

step 3.

1. Place the Bell Alarm mounting plate over the three

standoffs on the breaker front frame and secure

with three lock washers and nuts. Ensure that the

actuating tab from the breaker mechanism engages

the slot in the bottom of the mounting plate, as

illustrated in the front view in Figure 46.

2. Line up the Bell Alarm module on the mounting

plate, as shown in Figure 45, so that the solenoid

plunger and locating pin fit in the appropriate

holes. The label on the end of the module should

appear as in Figure 47, with the legend

SF LO

(

Small Frame Lockout) horizontal.

3. Attach the Bell Alarm module to the mounting

bracket with the two screws provided.

4. Run the four wires from the Bell Alarm to the secon-

dary disconnect A block and connect to the termi-

nals listed in Table 6. Use wire ties to secure the wire

bundle to the breaker frame.

5. Replace the breaker escutcheon, as described in Sec-

tion 7.5.

8.2 Shunt Trip

The Shunt Trip allows the breaker to be opened remotely

by the EntelliGuard Messenger™. It is always provided on

electrically operated breakers. The device causes the

circuit breaker to open when its coil is energized. An “A”

auxiliary switch, which is closed when the breaker is

closed, is connected in series with the Shunt Trip coil, as

illustrated in Figure 48. The voltage source is connected to

terminals 5 and 7 on the secondary disconnect.
Renewal parts for the Shunt Trip are a complete kit, illus-

trated in Figure 49, and the module. Electrical ratings for

the Shunt Trip are listed in Table 7.
