ENGLISH
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.
