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 61–035, or equivalent, available at most electrical
supply stores.
