EPO
This unit is equipped with provisions for the terminal connections for a UPS Emergency
Power OFF Switch (EPO). The terminal is located on the rear of the UPS next to the DB-9
connector. If an EPO switch is used, it must have the characteristics of an emergency but-
ton—closed under normal conditions and held open mechanically when operated. If this con-
nection is removed, the unit will not start up.
Connections must not exceed NEC Class 2 limits.
