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 Stan-
dard dealer to satisfy these requirements. Other well-
regulated 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.
Connect the RED power cable lead to the POSITIVE (+)
power supply terminal, and connect the BLACK power
cable lead to the NEGATIVE (–) power supply terminal.

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 oper-
ating from the Main Power Source a slight charging
current will maintain battery charge. In the event of an
unexpected interruption of the Main Power Source, the
automatic power control circuit will automatically
switch the repeater to the backup battery, and opera-
tion 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
requires approximately 7 amperes at 12 Volts during
transmit.
Never short the "Backup Power Sorce" Terminals,
when the Battery Charge switch (located on the PA
Unit) is set to "ON."
