Installation

WARNING: Before installing any accessories, turn the breaker
OFF, disconnect it from all voltage sources, and discharge the
charging springs.

AVERTISSEMENT: Avant d’installer tout accessoire, mettre
le disjoncteur en position OFF, le déconnecter de toute tension
d’alimentation, et décharger les ressorts d’armement.

The Bell Alarm–Alarm Only is installed in the accessory
compartment on the front of the circuit breaker in the position
shown in Figure 3.

Alarm–Alarm Only slot indicated.

Use the following procedure to install the Bell Alarm–Alarm
Only into the accessory compartment:

1. Open the hinged door over the accessory compartment and

Trip Unit.

2. To remove an existing accessory module, loosen the

accessory locking screw and pull the module out with the
Rating Plug Removal Tool (catalog number TRTOOL).

3. Insert the Bell Alarm–Alarm Only module into the proper

slot, as illustrated in Figure 4. The Bell Alarm–Alarm
Only module is keyed for the correct slot in the accessory
compartment. If the module cannot be fully seated in the
compartment, check that the compartment position is
correct.

4. Tighten the locking screw on the front of the accessory

until it is snug (9 in-lbs).

MicroVersaTrip PM Trip Unit, the Bell Alarm–Alarm
Only accessory can be configured to activate after trips
due to installed Undervoltage Release or Shunt Trip
accessories with the procedure described in the Accessory
Configuration section.

compartment and Trip Unit to prevent unauthorized
changes to Trip Unit settings and to keep contaminants
out of empty accessory slots.

Accessory Configuration

This section applies only if Shunt Trip or Undervoltage Release
accessories are installed in the breaker, along with a
MicroVersaTrip Plus or MicroVersaTrip PM Trip Unit. The
Bell Alarm–Alarm Only accessory can be configured to activate
if a Shunt Trip or Undervoltage Release trip occurs. The
configuration can be changed by removing the Trip Unit from
the breaker, setting the DIP switches on the rear of the Trip
Unit, and reinstalling the Trip Unit. Figure 5 illustrates the
Trip Unit rear DIP switches. Table 2 lists the switch functions
and the factory settings for each.
