2.3.4 Back Up Battery Port
This port connects to the ADRF-BBS/BBL-24 (24V battery backup unit) via a dedicated cable provided by the
ADRF.
Figure 2-7 Battery Backup Port
If an ADRF-BBS/BBL-24 is connected to the repeater, the battery switch on the PSU must be switched to the ON
position. This will enable the repeater to charge the ADRF-BBS/BBL-24 battery backup unit when AC power is
present.
Figure 2-8 Battery Switch
The PSR-78-9533 can be connected to an ADRF-BBS/BBL-24 to provide power during a power failure. If an ADRF-
BBS/BBL-24 is utilized, connect it to the PSR-78-9533 via the external battery port.
(WARNING: The circuit breaker switch on the ADRF-BBS/BBL-24 must be set to OFF before connecting it to
the PSR-78-9533 to prevent damage to the repeater or the ADRF-BBS/BBL-24 and personal injury.)
Note: Please contact ADRF Technical Support for assistance if you are unfamiliar with the installation procedure
of the battery box.
