2 Preparing for Installation
2.1 Safety Precautions
Note
To avoid personal injury and device damage, carefully read the safety precautions
before you install the device.
The following safety precautions may not cover all possible dangers.
2.1.1 General Safety Precautions
Do not expose the access point to high temperature, dusts, or harmful gases. Do not
install the access point in an inflammable or explosive environment. Keep the access
point away from EMI sources such as large radar stations, radio stations, and
substations. Do not subject the access point to unstable voltage, vibration, and noises.
The installation site should be free from water 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, electrical power, and transportation.
The installation site should be dry. It is not recommended that the access point be
installed in a place near the sea. Keep the device at least 500 meters away from the
ocean and do not face it towards the sea breeze.
Do not place the device in walking areas.
During the installation and maintenance, do not wear loose clothes, ornaments, or any
other things that may be hooked by the chassis.
Keep tools and components away from walking areas.
2.1.2 Handling Safety
Prevent the access point from being frequently handled.
Cut off all the power supplies and unplug all power cords before moving or handling
the device.
