Battery Back Up Installation
Refer to Figure 9-4. The installation procedures given in the kit drawing are those required for installing optional
battery back unit (part number 470639-0001/0002/0003) in supplied shelter.
Figure 9-4 Battery Backup Kit Installation
9.5.13
DC Voltage and Battery Installation
a. Insure VOR system AC and DC circuit breakers are in the OFF position.
b. Construct battery backup unit as detailed in Figure 11-25 or per the drawing provided with supplied battery
backup kit.
c. Install the four twelve-volt batteries and connect batteries in series using the short interconnect wires.
d. Install battery backup wiring between the VOR transmitter cabinet and the battery backup assembly. The
battery ground lead should connect to the grounding bus bar and the battery hot wire (+48V) should
connect to J1-1 Battery Connector located on the 1A7 Control Panel Assembly.
e. When supplied with two battery kits then connect the hot wire (+48V) from the second battery set to J1-2
Battery Connector located on the rear of the 1A7 Control Panel Assembly; otherwise connect both hot
wires to the one battery sets.
f. Install lid(s) on battery backup box.
CAUTION
Shorting the battery leads can cause a fire or explosion.
9.5.14
AC Voltage Installation
a. Set the primary AC power circuit breakers (located in the shelter main circuit breaker box) to the OFF
position.
b. Refer to Figure 1-4. Set DVOR SYSTEM A DC INPUT (BATTERY) and SYSTEM B DC INPUT
(BATTERY) circuit breakers to the OFF position.
c. Set DVOR SYSTEM A AC INPUT (LINE) and SYSTEM B AC INPUT (LINE) circuit breakers to the
OFF position.
d. Cut conduit and attach fittings as required to attach the conduit to the top.
e. Using No. 10 AWG stranded copper wire, fabricate system power line. Route system power line through
the conduit and into the DVOR transmitter cabinet to 1A7P1.
NOTE
The AC cables must not be routed in the same conduit as DC or signal wires.
