Temperature/Humidity Requirements
To ensure normal operation and prolong the service life of the device, the equipment room must maintain constant
temperature and humidity. If the equipment room is overheated for a long time, the insulation materials may result in
defective insulation and even electric leakage. If the relative humidity is low, the insulation spacer may result in dry
shrinkage, which will make screws looser and easily generate static electricity in the dry environment, thus damaging the
interior circuits on the device. Excessively high temperature will accelerate the aging of insulation materials and
compromise the reliability and even service life of the device. The temperature/humidity requirements are shown below
(detailed difference between products is described in the chapter of "Product Overview"):

The temperature/humidity of working atmosphere indicates the value measured at 1.5 m above the floor and
0.4 m ahead of the equipment frame when there is no protection plate on the front and rear side of the
equipment frame.
Short-term working condition refers to the continuous operation no exceeding 48 hours or accumulative
operations no exceeding 15 days in a year.
Extremely harsh working environment generally refers to the ambient temperature and humidity which may
be encountered when the equipment room air-conditioning system fails but will recover in less than 5 hours
every time.
Cleanliness Requirements
The dust is also a major threat to the safe operation of device. The dust accumulated on the device may cause
electrostatic adsorption and result in poor contact. It will not only compromise the service life of device but also cause
communication failure. When the indoor relative humidity is low, such electrostatic adsorption will incur more easily.

Apart from the dust, the device is also sensitive to the hydrochloric acid sulfide contained in the air. These noxious gases
will accelerate metal wastage and the aging of certain parts. The upper limits of noxious gases (Sulfur dioxide, Sulfured
hydrogen, Nitrogen dioxide, Ammonia and Chlorine) in the equipment room are shown in Table 2-3:
