Requirements for selecting the installation site
• Install the cabinet in a place free from high temperature, heavy dust, harmful gas, inflammable
or explosive material, electromagnetic interference (such as a large radar station, launching
tower, or transformer substation), unstable voltage, great shock (for example, near a railway).
• Ensure that the cabinet is installed at a place at least 500 meters away from the pollution
source, highways, and the seashore. Do not install the cabinet at erosion-prone areas such as
downwind direction of chemical plants, gas stations, foul ditches, fur factories.
• The installation site should be away from trees or other plants to reduce the possibility of air
intake vent blockage and ensure normal operation of the equipment.
• If the installation site is prone to snow accumulation, you are advised to increase the
installation foundation height to prevent the cabinet door from being blocked by snow.
• If the installation site is prone to snow accumulation, you are advised to increase the
installation foundation height to prevent water from entering the cabinet.
• To prevent the cabinet noise from affecting residents, it is recommended that the distance
between the installation site and households be greater than 10 m.
• Select a suitable place for the cabinet according to the telecom network plan and telecom
device requirements considering the hydrology, geology, earthquake, electric power, and traffic
