Optional Installation

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 shutdown of the UPS's
inverter.
Using the cable provided, connect the EPO port
of your UPS (see
closed or normally open switch according to the
circuit diagram (see
phone line surge suppressor; do not connect a
phone line to this port.
External Battery Connection

(Select Models Only)
Your UPS comes with a robust internal battery
system; external batteries are needed only to
extend runtime. Adding external batteries will
increase recharge time as well as runtime.
The illustration (see
your UPS's External Battery Connector
where you will insert the battery pack cable.
Complete installation instructions for your
battery pack appear in the battery pack 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 Switches (see
down position (High Charge Rate – External
Battery). This will increase your UPS's charger
output so that the additional batteries charge
faster.
Caution! DO NOT set the Battery Charge
Level Switches to the down position (High
Charge Rate – External Battery) without
an external battery connected. There is a
risk of damaging the UPS's internal battery
system.
Caution! When an external battery pack is
connected, make sure the AC load does not
exceed the nameplate rating. Some models
are derated when an external battery pack
is connected.
