Optional Installation

2 EPO Port Connection

This optional feature is only for those
applications which require connection to
a facility’s Emergency Power Off (EPO)
circuit. When the UPS is connected to
this circuit, it enables emergency	2a
shutdown of the UPS’s inverter.

Using the cable provided, connect the EPO port of your UPS (see 2a ) to a user- supplied normally closed or normally open switch according to the circuit diagram (see 2b ). The EPO port is not a phone line surge suppressor; do not connect a phone line to this port.

Connection

The SMART2500XLHG is equipped with an external battery capability for applications needing extended runtime. The back of the unit includes the external battery pack connector and charger rate switch. To access the connector, its factory-installed cover must be removed.

The charger rate switch is set to the internal battery setting (INT. BATT) by default. When using an external battery pack, the switch needs to be set to external battery setting (EXT. BATT). The connection of a battery pack and setting the switch can be done while the unit is operational.

Note: Leaving the charger rate switch on INT. BATT while connected to an external battery will not damage the unit. However, it will extend the time needed to recharge the batteries after a power event.
