INSTALLATION
_________________________________________________________________________________________________________
3.1.1 Environmental Considerations
The Airlink Venus hardware platform supports Airlink base station radio software, BS5000, or
Airlink remote radio software, Cobalt. The compact enclosure is designed for indoor operation
only. For outdoor use, it must be installed in a ventilated NEMA 4/4X enclosure of adequate size
and airflow to ensure the ambient environment of -40º F to 158º F (-40ºC to +70ºC) is
maintained. Humidity should not exceed 95% non-condensing for more than 96 hours with the
average humidity at 55%.
3.1.2 Equipment Ventilation
The Airlink Venus radio should be mounted in an area that allows for adequate air flow. The
radio should be mounted to maximize air flow around the heat sinks. For maximum cooling, the
radio should be mounted vertically to promote airflow over the fins. Provide adequate airflow
around the radio enclosure, maintaining a minimum 2-inch clearance from the front, sides, and
top surfaces. See Figure 3-2.
3.1.3 Site Grounding
Motorola's R56 site preparation practices provide the best source for grounding and lightning
preparation and should be consulted before equipment installation. It should be referred to for
grounding and lightning mitigation during this installation. Grounding and lightning protection are
important during equipment installation as grounding issues and damage to equipment from
lightning can cause significant issues if not done properly. Grounding and lightning protection
can be divided into the following categories:
●
Electrical Ground - Ground wires carrying current from equipment or circuitry at
the site ground. This includes AC or DC electrical power used to power
equipment at the site, backhaul connectivity, or alarm wiring.
●
Lightning Protection - Lightning protection and mitigation are crucial for safe and
reliable communications. This includes radio equipment, backhaul, coaxial cables,
networking cables, AC/DC cabling, etc. This is not only for equipment that is directly
onsite, but equipment where there's an electrical path from elsewhere to the site.
●
Surge Protection – It is critical to protect the equipment from electrical surges
that can occur from the power supply or source.
3.1.4 Input Power Requirements
The Airlink Venus radio requires an 18 to 60 VDC power input. The DC source must be capable
of supplying 2 amps and should be on a dedicated circuit protected with a fuse or circuit breaker
rated at 5 amps. Ensure wire of appropriate size is used.
