Shunt Trip

A shunt trip for the DC breaker on the battery cabinet is provided. This device is
operated with an applied voltage of 120VAC (supplied from the UPS). When this
voltage is applied, the shunt trip will cause the breaker to switch to the OFF position
disabling the battery cabinet.
7.2 NOTE: The EPO is achieved by completing the circuit between 14 &15 on terminal
block TB1 of the UPS. By completing the circuit, the shunt trip will cause the breaker
on the battery cabinet as well as the one on the UPS to switch to the OFF position
disabling the UPS and battery cabinet.
