VXR-9000V-H / VXR-9000U-H FM REPEATER OPERATING MANUAL
Power Supply
Operation of the VXR-9000x-H requires a power source
capable of providing at least 30 Amps continuously at
13.6 Volts DC. Please prepare the regulated power sup-
ply which satisfies the above voltage and current speci-
fications.
Use the DC power cable (VXSTD P/N: T9207279) sup-
plied with your repeater for making power connections
to the power supply. Connect the RED power cable lead
to the POSITIVE (+) power supply terminal, and con-
nect the BLACK power cable lead to the NEGATIVE (–
) power supply terminal.
INSTALLATION
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.
Never short the “Backup Power Sorce” Terminals,
when the Battery Charge switch (located on the
Relay Unit) is set to “ON.”
