Batteries

This chapter describes how to connect external batteries.

4.1 Cautions for Connecting External Batteries

yExternal 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.
