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.
3. Equipment Installation Methods
The CHU-P0BA00 may be mounted in a rack, bracket or cabinet, and may be placed on
your desk.
4. Site Grounding and Lightning Protection
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.
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 is
used to connect the repeater to the site grounding. All antenna cables, and AC and DC
power cords, should be properly grounded and lightning protected by following the rules
and guidelines provided in the above sections.
