CONNECTIONS
4. Connecting External
Battery Cabinet
(Optional)
External battery cabinets (EBC)
provide longer battery run-time
for connected devices. Refer to
GXT5 User Guide, to select the
appropriate model and quantity
for your GXT5 model and
applications.
• Verify that the EBC breaker
is in the “O” position.
• Connect one end of the
supplied EBC cable to the
UPS battery connector and
autodetect port (terminal
block 3) and one end to the
EBC’s battery connector and
autodetect port. If connecting
more than one EBC, connect
one end of the external
battery cable to the second
set of connectors on the
battery cabinet, then connect
the other end to the next
battery cabinet.
