3. Equipment Installation Methods
The this repeater may be mounted in a rack, bracket or
cabinet, and may be placed on your desk.
4. Site Grounding and Lightning Protection
The ground and lightning protection system is one of
the most important considerations when designing a
communication site. Proper grounding techniques and
lightning protection are closely related, and the general
category of site grounding may be divided into the
following two sections:
Electrical Ground
Ground wires carrying electrical current from circuitry
or equipment at the site are included in the category of
electrical ground. Examples include the AC and DC power
used to source equipment located at the site, and wires or
cables connected to alarms or sensors located at the site.
Lightning Ground
Providing adequate lightning protection is critical to a safe
reliable communication site. The repeater is equipped
with a ground screw located on the rear panel. This screw

Caution: Proper site grounding and lightning
protection are vitally important considerations.
Failure to provide proper lightning protection may
result in permanent damage to the repeater.
Caution: If the repeater is to be installed in an area
which is usually dusty, dirty, or does not meet the air
quality requirements, then the air used to cool the
repeater modules must be treated using appropriate
filtering devices. Dust or dirt accumulated on the
internal circuit boards and modules is not easily
removed, and can cause malfunctions such as
overheating and intermittent electrical connections.
2. Equipment Ventilation
The PA heatsink is equipped with a cooling fan used to
provide forced convection cooling. When planning the
installation, observe the following ventilation guidelines:
Customer supplied cabinets must be equipped with
ventilation slots or openings for air to enter and exit.
If several repeaters are installed in a single cabinet,
ensure ventilation openings surrounding each repeater
allow for adequate cooling.
All cabinets must have at least 10cm of open space
between the air vents and any wall or other objects.
When multiple cabinets (each equipped with several
repeaters) are installed in an enclosed area, ensure
appropriate ventilation and consider air conditioning
or other climate control equipment, to satisfy the
temperature requirements stated above.
