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. WARNING To AVOID damaging gas, power or other underground utility CAUTION lines, contact underground utility locating companies BEFORE digging more than 18" (46 cm) deep. Single piece of 12 gauge copper wire attached to the operator's chassis ground. Check local codes for proper depth. AVERT AVERT ATTEN AVER ADVERTENCIA PRECAUCIÓN 21
