If the breaker is equipped with a MicroVersaTrip Plus
or MicroVersaTrip PM Trip Unit, the Shunt Trip
accessory can be configured to activate installed Bell
Alarm-Alarm Only or Bell Alarm with Lockout
accessories when a shunt trip occurs, with the
procedure described in the Accessory Configuration
section.
Connect the control wiring for either Shunt Trip to
terminals 31 and 32 at the terminal block on the right
side of the breaker.
Test to ensure proper operation, according to the
procedures below.
Reconnect power to the circuit breaker and any other
accessories.
Close and lock or seal the door over the accessory
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 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 Shunt Trip accessory can be configured to activate the
Bell Alarm-Alarm Only or Bell Alarm with Lockout accessories if
a shunt 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 and
their functions. Table 3 lists the switch functions and the
factory settings for each.
