4.3 Connecting External Batteries

4.3.1 Cautions for Connecting External Batteries

External batteries are required to maintain stable operation of the OfficeServ 7030 system in
case of a power failure occurs. The capacity for this battery should be rated at DC 48V. A fuse
(125VAC, 3Amp) should be positioned between the output terminal of the battery and the
cabinet.
Cautions for connecting external batteries
Do not connect external AC power to the system before completing the connection between
batteries and the system. If so, it may cause electric shock.
Check the specified polarity (+ or -) to connect external batteries.
To reduce risk of fire and injury, use only a sealed nickel cadmium or lead-acid battery supply
capable of handling a charge current of .5A, a charge voltage of -54V DC, and a discharge rate
of 26Ah.
Observe the following precautions when installing batteries:
Make sure the batteries you install conform to local building, fire and safety codes. Some

battery types emit hydrogen gas during the charging state and may require venting to
fresh air.
Do not place batteries directly on a concrete floor. This causes them to discharge very

quickly.
Follow the battery manufacturer's recommended installation and maintenance

procedures.

4.3.2 Procedure for Connecting External Battery

The procedure for using a battery cable to connect an external battery to the OfficeServ 7030
system is as follows:
1) Use the battery cable that was provided with the OfficeServ 7030 system. The battery
cable consists of a red wire and a black wire.
2) Connect the red wire of the locally provided battery cable to the (+) terminal, and the
black wire the (-) terminal of the battery. Connect the other end of the battery cable to the
external battery socket on the two prong connector on the supply of the OfficeServ 7030
cabinet. (See figure 4-5).
