Backup Batteries Connection
The backup batteries and Back-up Battery Cable provide a backup power supply to allow full
use of the Hybrid IP-PBX in the event of a power failure. In case of power failure, the backup
batteries automatically maintain the power to the Hybrid IP-PBX without interruption.
Turn off the power switch of the Hybrid IP-PBX.
Connect the Back-up Battery Cable with 3 identical VRLA (Valve Regulated Lead Acid)
batteries (12 V DC × 3).
Turn on the power switch of the Hybrid IP-PBX only after the installation of the Hybrid IP-
PBX is finished and AC power is available.
For each backup battery, battery capacity of 14 Ah or below is recommended (otherwise,
the battery charge may not be maintained).
Make sure that the type and capacity of the 3 backup batteries are identical.
The Back-up Battery Cable should not be exposed to direct sunlight. Keep the Back-up
Battery Cable and the backup batteries away from heating appliances and fire. Place the
backup batteries in ventilated place.
For details about the backup batteries, refer to the manual intended for the batteries.
Be sure to comply with applicable local regulations (e.g., law, guidelines).
Make sure that the polarities of the backup batteries and wiring are correct.
Make sure that you do not short the backup batteries or cables.
There is a danger of explosion if backup batteries are incorrectly replaced. Replace
only with the same or equivalent type recommended by the battery manufacturer.
Dispose of used batteries according to the manufacturer's instructions.
