Wiring to the AC Transformer must not exceed 250 feet using 16 gauge wire.
Do not plug the transformer into the AC outlet until you are instructed to do so
later in the manual.
Do not attach the connector cable to the battery terminals until you are
instructed to do so later in the manual.
1. Place the 12-volt back-up battery in the control cabinet.
2. Attach Red and Black wires on the battery connector cable to the control
board as follows: †
a. Red to the positive (+) battery tab on the control board (see Summary
of Connections Diagram for location, if necessary).
b. Black to the negative (–) battery tab on the control board.
†
These wires may have already been connected to the battery tabs on the control
board. If so, disregard steps a. and b.
DO NOT CONNECT THE WIRES TO THE BATTERY YET!
Use a 4AH battery or larger for UL installations.
The designated earth ground terminal (21), must be terminated in a good earth
ground for the lightning transient protective devices in this product to be
effective. The following are examples of good earth grounds available at most
installations:
Metal Cold Water Pipe:
Use a non-corrosive metal strap (copper is recommended) firmly secured to
the pipe to which the ground lead is electrically connected and secured.
AC Power Outlet Ground:
Available from 3-prong, 120VAC, power outlets only. To test the integrity of the
ground terminal, use a three-wire circuit tester with neon lamp indicators, such
as the UL-Listed Ideal Model 61–035, or equivalent, available at most electrical
supply stores.
