To ensure personal and equipment safety, observe all the safety 
precautions on the equipmentand in this document.                                            
and                 and items do not cover all the safety precautions and 
are only supplementary to the safety precautions.
The device needs to be installed in a clean, dry, well ventilated, and 
temperature-controllable standard equipment room.In addition, the 
equipment room must be free from leaking or dripping water, heavy 
dew, and condensing.
Dustproof measures must be taken in the installation site. This is 
because dust will cause electrostatic discharges on the device and aect 
connections of metal connectors and joints, shortening the service life 
of the device and even resulting in device failures.
The installation site must be free from acidic, alkaline, and other types 
of corrosive gases.
The device that is operating may cause radio interference. If this is the 
case, relevant measures may be needed to reduce the interference.
Generally, devices such as wireless antennas should not be installed in 
the equipment room. If such devices must be installed indoors, ensure 
that the electromagnetic environment meets relevant requirements or 
take necessary electromagnetic shielding measures.
The device to be installed must be used indoors. To ensure normal 
operation and long service life of the device, the following requirements 
must be met:
The temperature and humidity in the installation site must meet device 
requirements described in the following table.
Long-term operating 
temperature [°C]
Relative operating 
humidity [RH]
–40°C to +65°C
≤ 4000 m (For the altitude in the range of 1800 m to 
4000 m, the operating temperature ofthe device 
decreases by 1°C every time the altitude increases 
by 220 m.)
