Grounding
Connect a heavy gauge (#10AWG) copper wire to the earth ground
lug on the left end of the panel and connect the other end to a
ground rod or metal cold water pipe (See Figure 3). It is extremely
important that the earth ground connection be as short as possible.
The ground rod should have sufficient depth to provide a low
impedance connection to earth. This connection is required for the
surge/lightning protection circuits to function properly.
NOTE: Proper earth grounding of the 1800 is
required for warranty coverage.
Ground rods can typically be found at local electrical supply houses
and/or hardware stores. Be sure to contact your state “Call before
you dig” hotline at least
two days before you install your ground
rod, to insure that it is safe to install the ground rod in a chosen area.
