If you install the AP on a desk, none of the above tools is required. If you install the AP on top of or under
eave of a building, no digging tool is required.
Examining the Installation Site
Before installation, examine the installation site to make sure that the AP will work in a good
environment. You can examine the installation site from the following three aspects.
Installation Site Selection
Keep the AP away from places that are susceptible to high temperature, dust, inflammable, explosive,
electromagnetic interference (high power radar, radio station, and transformer), unstable voltage, heavy
vibration, or loud noise. The installation site should be dry, without any leakage, dripping, or dew. The
AP should be at least 500 m (0.31 mi) away from the seaside and should not face the direction of sea
wind.
In engineering design, the site should be selected according to the network planning and technical
requirements of communications equipment, as well as the considerations such as climate, hydrology,
geology, earthquake, electric power, and transportation.
Temperature and Humidity Requirements
The temperature and humidity requirements depend on your AP model. For more information, see the
installation guide or quick start of your AP.
Power Supply
The power supply mode depends on your AP model. For more information, see the installation guide or
quick start of your AP.
Grounding and Lightning Protection

Grounding
resistance
z The earth resistance is usually required to be less than 5 ohms, and less than 10
ohms in an area with less than 20 thunderstorm days a year. If a piece of angle steel
is buried as the earthing conductor, the earth resistance is required to be less than 10
ohms. In an area with a higher earth resistance, reduce the earth resistance by using
brine or resistance reducing agent around the earthing conductor.
z The top of the earthing conductor should be at least 0.7 m (2.30 ft) away from the
ground surface. In cold areas, the earthing conductor should be buried below the
frozen soil layer.
