Overvoltage (Lightning/Surge) Protection
WARNING!
A qualified professional installer should install the wireless equipment.
The installer must follow local and national codes for electrical
grounding and safety. Failure to meet safety requirements and/or use
of non-standard practices and procedures could result in personal
injury and damage to equipment. A direct lightning strike may cause
serious damage even if these guidelines are followed.
All outdoor wireless equipment is susceptible to lightning damage from a direct hit or induced current
from a near strike. Lightning protection and grounding practices in local and national electrical codes
serve to minimize equipment damage, service outages and serious injury. Reasons for lightning damage
can be summarized as follows:
Poorly grounded antenna sites that can conduct high lightning strike energy into equipment.
Lack of properly installed lightning protection equipment that can cause equipment failures from
lightning induced currents.
An overvoltage protection system provides a means by which the energy may enter earth without
passing through and damaging parts of a structure. An overvoltage protection system does not prevent
lightning from striking; it provides a means for controlling it and preventing damage by providing a low
resistance path for the discharge of energy to travel safely to ground. Improperly grounded connections
are also a source of noise that can cause sensitive equipment to malfunction.
A good grounding system disperses most of the surge energy from a lightning strike away from the
building and equipment. The remaining energy on the cable can be directed safely to ground through a
lightning/surge arrestor in series with the cable.
