2 Preparing for Installation
To prevent device damage and physical injury, please read the safety recommendations carefully as described in this
chapter.
Suggestions do not cover all possible hazardous situations.
2.1 Lightning Protection
When the connection cable between the main grounding conductor and local equipotential earthing terminal board
(LEB) on each floor is shorter than 2 meters, use a stranded copper wire with a sectional area not less than 1.318
mm
2
(16 AWG) for the connection cable.
Use a shielded network cable if possible, ensure that devices connected to both ends of the shielded network cable
are reliably grounded, and make sure that the sheath of the shielded network cable is also grounded if possible. If no
shielded network cable is available, wire the network cable through a steel pipe and bury the steel pipe for lead-in,
and properly ground both ends of the steel pipe.
No additional lightning protector is required as a high-profile lightning protector is built in the RG-EST350 and the
antenna port and power port support 4kV lightning protection. If a lightning protector of a higher profile is available,
configure the lightning protector optionally. Before the configuration, connect the lightning protector to the ground
cable.
2.2 Installation Site
Do not expose the device to high temperature, dust, or harmful gases.
Do not install the device in an area prone to fire or explosions.
Keep the device away from EMI sources such as large radar stations, radio stations, and substations.
Do not subject the device to unstable voltage, vibration, and noises.
Keep the device at least 500 meters away from the ocean and do not face it towards the sea breeze.
The installation site should be protected from water and flooding, seepage, dripping, or condensation.
The installation site should be selected according to network planning, communications equipment features and
considerations such as climate, hydrology, geology, earthquake, electric power, and transportation.
2.2.1 Temperature and Humidity
To ensure the normal operation and equipment service life, maintain appropriate temperature and humidity levels in the
equipment room. See Table 2-1.
Table 2-1 Temperature and Humidity Requirement
Working Temperature
-30°C to 65°C (-22°F to 149°F)
Working Humidity
5% to 95% (non-condensing)
