Procedure for Changing Switch Settings

Change the accessory switch settings with the following
procedure:

WARNING: Before beginning this procedure, turn the breaker
off, disconnect it from all voltage sources, and discharge the
closing springs.

AVERTISSEMENT: Avant de commencer cette procédure,
mettre le disjoncteur en position OFF, le déconnecter de toute
tension d’alimentation, et désarmer les ressorts de fermeture.

1. Loosen the four #8-32 screws on the breaker trim-plate

assembly and remove the trim plate.

2. Loosen the four #10-32 screws at the corner of the breaker

cover. Remove the cover from the breaker face.

3. Pull the Trip Unit locking lever to the right, then hold the

Trip Unit near the battery cover and lift it straight out of
the breaker.

4. Refer to Figure 5 and Table 2 to determine the switches

to be changed.

5. Push in the appropriate “Enable” or “Disable” side of the

switch.

6. Confirm all switch settings before reinstalling the Trip

Unit in the breaker.

7. Pull the Trip Unit locking lever to the right. While

holding the lever, carefully align the connector on the rear
of the Trip Unit with the connector in the breaker. Press
down on the Trip Unit, while holding it near the battery
cover. When the Trip Unit is fully seated, slide the locking
lever back to the left.

8. Reinstall the breaker top cover and tighten the four #10-

32 screws to 32 in-lbs.

9. Replace the trim plate and tighten the four #8-32 screws

to 20 in-lbs.

10. Verify that the switch settings are correct by inducing

breaker trips from the UVR and/or Shunt Trip (if
present) and checking the responses of the Bell
Alarm–Alarm Only and Bell Alarm with Lockout
accessories.
