Installing the Backup Battery
Place the 12-volt backup battery in the control cabinet. To calculate the correct battery size
for an installation, refer temporarily to "Calculating the Battery Size Needed" in Section 10:
FINAL POWER-UP.
Do not attach the connector cable to the terminals on the battery until you are instructed to do so
later in the manual.
Earth Ground Connections
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 noncorrosive metal strap (copper is recommended) firmly secured to the pipe to which
the ground lead is electrically connected and secured.
Earth Ground Rod:
Use a copper rod driven far enough into the ground to assure that good earthing has been
achieved.
