APPENDIX D
BATTERY BACK-UP OPTION
1. OVERVIEW
The SelectAmp series repeaters can be provided with an optional battery back-up, 65ACCE-XXXX-000. This
unit is designed to provide the repeater with a minimum of two hours of operation after loss of AC power.
This two-hour life rating is for full current draw at –40
o
C, so the actual operating life will be dependent on
traffic load and ambient temperature at the time the battery back-up is engaged. The unit contains two
batteries, a battery charger, and ancillary components for internal temperature control. There are two
external connections, one for AC power and one for DC interconnect between the battery back-up and the
repeater. The connections are opposite sex to reduce the possibility of swapping power inputs. A 12 foot AC
power cord and a 6 foot DC interconnect cable is shipped with the unit.
2. INSTALLATION
CAUTION
THIS UNIT IS EXTREMELY HEAVY. USE CARE WHEN LIFTING.
CAUTION
Installation requires only sufficient structural strength of the installation site to support the weight of the
unit. The unit should be mounted within 10 feet of an AC power source, and within 5 feet of the
repeater.
