This chapter describes how to connect external batteries.

4.1 Cautions for Connecting External Batteries

External batteries are required to ensure stable operation of the OfficeServ 7100
system in case a power failure occurs. The rated capacity of an external battery is DC
48V per cabinet. Batteries should be connected to each cabinet to guarantee safety and
a fuse(125 VAC, 5 A) should be positioned between the output terminal of the battery
and the battery connector of the cabinet
Cautions for connecting an external battery
Do not connect external AC power to the system before connecting an external
battery to the system. To do so, may cause electric shock for the system or the
constructor.
Make sure that the polarities(+/-) between the external battery ant the system are
equal.
To reduce risk of fire and injury to persons, use only a sealed nickel cadmium or
lead-acid battery supply capable of handling a charge current of 0.25 A, a charge
voltage of -54 V dc and a discharge rate of 26 Ah.
