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 noncorrosive 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 3-wire circuit tester with neon lamp indicators, such
as the UL Listed Ideal Model 61035, or equivalent, available at most electrical supply stores.
