CAUTIONS FOR CONNECTING EXTERNAL BATTERIES
External batteries are required to maintain stable operation of the OfficeServ 7100
system in case a power failure occurs. The capacity for this battery should be rated at
DC 48 V. A fuse (125 VAC, 5 Amp) 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 0.25A, a charge voltage
of —54 V DC, and a discharge rate of 26 Ah.
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.
