b. Wire the other three terminals (Sync, Data, Com) on the 4300
transformer. Wires from these terminals must be connected to a 9-pin
connector on the control board (using a 4142TR cable supplied with the
4300 transformer), as shown in Figure 5. These particular wires can be
24 gauge or larger, and can be run along with the AC and ground wires
to the control panel.

Installing The Back-Up Battery

If necessary, refer to the FINAL POWER UP section for information
regarding battery size to use, etc.
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 as follows:
a. Red to the positive (+) battery terminal on the control board (see
Summary of Connections Diagram for location, if necessary).
b. Black to the negative (Ð) battery terminal on the control board.

Use a 4AH battery or larger for UL installations.

Earth Ground Connections

The designated earth ground terminal (25), 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 61Ð035 ,
or equivalent, available at most electrical supply stores.
