Accessory Configuration
This section only applies if Bell Alarm–Alarm Only or Bell
Alarm with Lockout accessories are installed in the breaker,
along with a MicroVersaTrip Plus or MicroVersaTrip PM Trip
Unit. If the breaker is equipped with a Power+ Trip Unit, the
factory default settings, listed in Table 3, can not be changed.
The UVR accessory can be configured to activate the Bell
Alarm–Alarm Only or Bell Alarm with Lockout accessories if a
UVR 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 4
illustrates the Trip Unit read DIP switches and their functions.
Table 3 lists the switch functions and the factory settings for
each.
