Lightning Protection

WARNING: This user manual provides notes are general recommendations for the
system. The wireless equipment should be installed by a qualified professional installer
who is knowledgeable of and follows 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.
All outdoor wireless equipment is susceptible to lightning damage from a direct hit or
induced current from a near strike. A direct lightning strike may cause serious damage
even if these guidelines are followed. 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 are summarized as:
- Poorly grounded antenna sites that can conduct high lightning strike energy into
equipment.
- Lack of properly installed lightning protection equipment can cause equipment
failures from lightning induced currents.
A lighting protection system provides a means by which the energy may enter earth
without passing through and damaging parts of a structure. A lightning protection system
does not prevent lightning from striking; it provides a means for preventing damage to
equipment 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 Ethernet cable
shield and conductors can be directed safely to ground by installing a lightning arrestor
in series with the cable.
If you have determined that it is appropriate to install lightning protection for your system,
the following general industry practices are provided as a guideline only:
The AC wall outlet ground for the indoor POE adapter should be connected to the
1.
building grounding system.
Install a lightning arrestor in series with the Ethernet cable at the point of entry to the
2.
building. The grounding wire should be connected to the same termination point
used for the tower or mast.
Provide direct grounding connections from the RDL-3000, the mounting bracket, the
3.
antenna, and the Ethernet cable surge protection to the common building ground
bus. Use the grounding screws provided for terminating the ground wires.
