Grounding Guidelines
Proper grounding protects both your SecureMesh device and any equipment connected to it. For the surge
protection circuitry built into the SecureMesh equipment to be effective, proper grounding of the unit is
necessary. Protection is essential if the unit is installed on tall structures or in areas subject to lightning.
Note that the techniques described in this appendix are intended as general guidelines and do not constitute a
comprehensive guide covering all installation scenarios. For maximum protection, contact a qualified
installation specialist who is familiar with your operating environments. If lightning is a threat in your area,
consider a consultation with a lightning and transient protection specialist.
General Grounding Strategy
To ensure optimal reliability, properly ground the metal base of the SecureMesh device. The most efficient
way to ground the device is to use a 10 AWG or larger wire to connect it to a ground point on the structure or
tower.
The three most common grounding points are:
The primary grounding point or the down lead
provided by an existing grounding system at the
installation site. For example, the grounding
system may be provided by a building's AC
electrical system
, a streetlight’s power system,
or as part of a tower structure.
A 10-foot or longer copper-clad ground rod
driven into the earth. At a tower with multiple
legs, there will typically be one ground rod per
leg and a ground wire loop connecting each of
the rods as shown in the accompanying picture.
A cold-water pipe. Make sure it is well
connected to earth.
