Earth Ground Rod Installation - Chamberlain LiftMaster Professional SL585GL Manual

EARTH GROUND ROD INSTALLATION

Proper grounding gives an electrical charge, such as from an
electrical static discharge or a near lightning strike, a path from
which to dissipate its energy safely into the earth.
Without this path, the intense energy generated by lightning could
be directed towards the gate operator. Although nothing can
absorb the tremendous power of a direct lightning strike, proper
grounding can protect the gate operator in most cases.
The earth ground rod must be located within 3 feet from the gate
operator. Use the proper type earth ground rod for your local
area.
The ground wire must be a single, whole piece of wire. Never
splice two wires for the ground wire. If you should cut the ground
wire too short, break it, or destroy its integrity, replace it with a
single wire length.
