Introduction
During brownouts, blackouts, and other power interruptions, battery cabinets provide
emergency DC power to the UPS to safeguard operation of the critical load.
The Integrated Battery Cabinet (IBC) systems are housed in single free‐standing cabinets.
Two models are available: Model IBC-S (small cabinet) and Model IBC-L (large cabinet).
Each model features three battery voltage ranges to meet application run time needs. Up
to four cabinets may be daisy-chained together to further extend battery run times. The
cabinets match the UPS cabinet in style and color, and can be installed in
line-up-and-match or
stand‐alone
configurations. Figure 1‐1 depicts the Powerware

Model IBC-S and Figure 1‐2 depicts the Powerware 9390 Model IBC-L.
Mechanical lugs, located at the front of the cabinet, reduce installation time, and
removable battery trays with
quick disconnects between trays reduce battery maintenance
time. A DC-rated circuit breaker within each cabinet provides protection and servicing
isolation.
