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
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 protector; 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. Use only Tripp Lite external
battery packs with overcurrent protection.
Adding external batteries will increase recharge
time as well as runtime.
The illustration (see
3a
) shows the location of
your UPS’s External Battery Connector
A
,
where you will insert the battery pack cable.
Installation should be performed by qualified
service personnel only. See the battery pack
owner’s manual for complete installation
instructions. Make sure 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.
