Installation Procedures

This section describes recommendations for grounding and line protection equipment,
mounting the RDL-3000, RF and Ethernet connections, basic wireless configuration, and
alignment of the antenna.
5.1

General Guidelines

All outdoor wireless equipment is susceptible to lightning damage from a direct hit or
current induced from a near strike. Surge protection and grounding practices described
in local and national electrical codes are intended to prevent serious injury, minimize
damage to equipment, and reduce service outages.
CAUTION: The following are general recommendations for system installation.
This equipment must be installed by a qualified professional installer and 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 injury or serious damage
regardless if all recommendations are observed during system installation.
5.1.1

Grounding

A good grounding system disperses most of the lightning strike surge energy away from
the building and equipment.
Provide direct grounding connections from the RDL-3000, mounting bracket, and
1.
antenna (if mounted separately) to the master ground for the tower or mast. Use the
grounding screws provided for terminating the ground wires.
The AC wall outlet ground for the indoor POE adapter should be connected to the
2.
master ground bus for the building.
The following general industry practices are provided as a guideline only:
3.
- All grounding connections must conform to local/national standards.
- Above ground wire must be #2-6 AWG when interconnecting ground rings and
#6 AWG (minimum) for grounding equipment and metal objects
- Below ground wire must be #2 AWG (minimum).
- Ground rods must be 2.44 m (8 ft) long (minimum) and 15.875 mm (5/8 in) in
diameter and extend 0.92 m (3 ft) below any adjacent basement/vault.
- A grounding block should be installed where cables enter the building.
- Painted or dirty surfaces should be cleaned thoroughly down to bare metal and
screws well tightened.
- Ground wires should not have sharp bends.
- The installation site should have an external ground ring or bus bar.
