Lift-Master EARTH GROUND ROD User 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 Phone system. Although nothing can absorb the tremendous power of a
direct lightning strike, proper grounding can protect the Phone system in most
cases.

The type and length of earth ground rods vary by region. Contact the building
inspector’s office in the municipality where you plan to install the unit for correct
grounding materials and installation procedures.

Before digging, contact local underground utility locating companies.

Avoid damaging gas, power, or other underground utility lines.

The earth ground rod must be located within 3 feet from the Phone system.

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.

The earth ground rod must be located within
3 feet from the equipment being grounded.
