RDL-2000 Installation Guidelines

4.5.2 System Grounding

A grounding connection is located on the RDL-2000 chassis. Use this screw to terminate

a grounding wire.

System Grounding Procedures

Correct grounding is very important for safe operation of wireless equipment -- ensure

that all grounding connections are made in accordance with local and national

standards.

The following general industry practices are provided as a guideline only:

1. All grounding connections must be made in accordance with local and national

standards. Painted or dirty surfaces should be cleaned thoroughly down to bare

metal and screws should be well tightened.

2. Provide a direct ground connection from the antenna-mounting bracket, the RDL-

2000 unit, and any lightning protection equipment, to the same

ground point on the

tower. Use the grounding screw on the antenna bracket and the grounding screw on

the RDL-2000 to terminate the ground wires. Avoid making sharp bends in the

ground wires.

4.5.3 Lightning Protection Guidelines

All outdoor wireless equipment is susceptible to lightning damage. Lightning protection

and grounding practices per the local and national electrical codes serve to minimize

possible equipment damage, service outages, and serious injury. Common reasons for

these damages can be summarized as follows:

- Tower/Antenna sites that are not grounded properly may conduct high lightning strike

energy.

- Lack of installed lightning protection equipment may cause equipment failures

resulting from lightning induced currents.

The grounding system should provide a low-impedance path to ground for the lightning-

induced current. A loose ground connection is a source of noise and may cause

sensitive equipment to malfunction.

The tower grounding system disperses most of the surge energy from a tower strike

away from the building and equipment. The remaining energy on the Ethernet cable

shield and center conductor can be directed safely to ground by using a lightning

arrestor in series with the Ethernet cable.

Grounding Guidelines

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 hit may

cause serious damage or i njury even if these guidelines are followed for the

system.

The following general industry practices are provided as a guideline only.

- All grounding connections must

be made in accordance with local/national

standards.

- Painted or dirty surfaces should be cleaned thoroughly down to bare metal and

screws should be well tightened.
