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 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 61035, or equivalent, available at most electrical supply stores.
