Backup Power Supply - Vertex Standard VXR-9000 Operating Manual

NSTALLATION
Power Supply
Operation of the VXR-9000 requires a power source ca-
pable of providing at least 12 Amps continuously at 13.6
Volts DC. The FP-1023 (23 A) and FP-1030A (30 A) AC
Power Supplies are available from your Vertex Standard
dealer to satisfy these requirements. Other well-regu-
lated power supplies may be used, as well, if they meet
the above voltage and current specifications.
Use the DC power cable supplied with your repeater
for making power connections to the power supply. Con-
nect the RED power cable lead to the POSITIVE (+)
power supply terminal, and connect the BLACK power
cable lead to the NEGATIVE (–) power supply termi-
nal.

Backup Power Supply

For uninterrupted operation during power failures, a
12-volt rechargeable type battery (55-Ah or more rec-
ommended) may be connected to the BACKUP termi-
nal posts on the rear panel. While the repeater is operat-
ing from the Main Power Source a slight charging cur-
rent will maintain battery charge. In the event of an un-
expected interruption of the Main Power Source, the
automatic power control circuit will automatically
switch the repeater to the backup battery, and operation
will not be interrupted.
After prolonged operation from the battery, (Backup
Power Source), it should be disconnected from the re-
peater and recharged separately before re-connecting,
as the trickle charge is not sufficient for recharging a
completely discharged battery.
Never reapply the Main Power Source to the repeater
with a discharged battery connected as backup, as the
DC startup current can damage the repeater and bat-
tery.
While operating from a backup battery, the repeater re-
quires approximately 7 amperes at 12 Volts during trans-
mit.
Never short the "Backup Power Sorce" Terminals,
when the Battery Charge switch (located on the
PA Unit) is set to "ON."
