OSHA Safety Standards
The United States Department of Labor, through the provisions of the
Occupational Safety and Health Act, has established an electromagnetic energy
safety standard with applies to the use of this equipment. Proper use of this
radio equipment will result in exposure below the OSHA limit. The following
precautions are recommended:
DO NOT operate the transmitter of a fixed radio (base station, radio paging
transmitter RF equipment) when someone is within two feet (0.6 meters) of the
antenna.
DO NOT operate the transmitter of any radio unless all RF connectors are secure
and any open connectors are properly terminated.
In addition, all equipment must be properly grounded according to National &
Local Electrical Codes.
Lightning Protection Considerations
The Transmitters and Power Amplifiers have protection against high voltages but
for all external connections, added protection against lightning attack should be
considered. For Transmitters used for high power applications with tower
antennas, the following measures will provide sufficient protection against minor
lighting attacks.
− Keep the antenna tower grounding resistance as low as possible.
− The ground rods should be made of copper and be at least eight feet
long. Multiple rods should be used over a single rod, if possible.
− All transmission line bends should be made according to
manufacturer’s exact specifications. All ground line bend should be
made as large as possible.
− Ground the transmission line sheath at every opportunity. Also,
ground the transmission line where it is supported on poles and where
it enters the building.
− Whenever possible, run at least a part of the transmission line through
a length of ground conduit.
− Tie all equipment grounds together to a single point. Then, ground that
point to a grounding rod using as short and as straight a ground wire
as possible.
− The ground wire must never be bundled with other wires in the system.
Also, ground wires must not run along a metal plane.
