CSW / SL Surge Protection Module for Non-OmniControl Commercial Gate Operators
Please read this entire manual before installation
Chamberlain Professional Products strongly recommends the installation
of this Surge Protection Module to protect the gate operator from harmful
surges caused by lightning strike phenomenon.
It is important to recognize that the surge protection module may not
prevent damage to the gate operator in the event of a direct lightning
strike.
The success of the surge protection will be based in the proper installation
of the Surge Protection Module and the proper grounding of both the
surge protector module and the gate operator itself.
This Surge Protection Module will provide protection for the following input commands.
Name of Lines Protected
External Safety Loop “Command” input

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.
Before digging more than 18" deep, 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 gate
operator. Use the proper type earth ground rod for your 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.
Chamberlain Professional Products, Inc. is not responsible
for improper installation or failure to comply with all
necessary local building codes.
