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.
