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 shutdown of the UPS's inverter.

Using the cable provided, connect the EPO port of your UPS (see 4a ) to a user-supplied normally closed or normally open switch according to the circuit diagram (see 4b ). The EPO port is not a phone line surge suppressor; do not connect a phone line to this port.

3	External Battery Connection
	(select models)
	Your UPS comes with a robust internal battery
	system; external batteries are only needed to
	extend runtime. Adding external batteries will
	increase recharge time as well as runtime.
	The illustration (see		) shows the location of your
		3a
	UPS’s External Battery Connector, where you will
	insert the battery pack cable. Complete installation					3a
	instructions for your battery pack appear in the battery
	pack’s owner’s manual. Make sure that cables are
	fully inserted into their connectors. Small sparks
	may result during battery connection; this is normal.
	Do not connect or disconnect battery packs when
	the UPS is running on battery power.
	If you connect any external batteries, set the
	Battery Charge Level Switch (see			3b	) to the up
	position. This will increase your UPS’s charger
	output so the additional batteries charge faster.
						3b
	Note: the switch to the right of the Battery Charge
	Level Switch is inactive and will not affect UPS
	operation regardless of its position.

CAUTION! DO NOT set the Battery Charge Level Switch to the up position without an external battery con- nected. There is a risk of damaging the UPS’s internal battery system.
