INSTALLATION
Grounding
The Extended Battery Cabinet must be installed
with a dedicated grounding electrode conductor
(GEC) to the site grounding system in accordance
with national and local wiring codes and regulations
as shown below.
Communications
To enable communication between the Extended
Battery Cabinet and the
Nfinity , it is necessary to
install an Intellislot Battery Card (IBC) in the
Intellislot port of the UPS. See below. A second,
included IBC is installed in the Extended Battery
Cabinet. The provided serial cable is to be
connected between the two cards.
DC Power
DC connection with the UPS unit must be via the
factory-supplied battery cables, or if longer
connection cable is required, via the optional
Extended Battery Cable kits. See below.
After connections are made and verified, the
output circuit breaker must be closed to connect
the batteries inside the Extended Battery Cabinet
to the Nfinity UPS. To do this, move the handle of
the circuit breaker under the lower-most bezel to
the ON position
(see illustration below for circuit
breaker location).
