This optional feature is only for those

suppressor; do not connect a phone line to
this port.
4 External Battery Connection
(select models)
Check to ensure that the external batteries you
are connecting match the voltage listed on
your UPS's battery connector. All UPS models
come with a robust internal battery system;
select models feature connectors that accept
optional external battery packs (sold separately
from Tripp Lite) to provide additional runtime.
Adding external batteries will increase
recharge time as well as runtime. 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.
