Other than dust, the content of salt, acid and sulfide in the air should also
be restricted to meet the requirements of switch's working environment,
since such harmful gases will aggravate metal corrosion and the aging of
some parts. The working environment should be free of harmful gases,
like SO2, H2S, NO2, NH3 and Cl2, and etc. The table below demonstrates
the recommended threshold of those gases:

Te mp e r a tu r e a nd Hum i di t y
For a good air circulation after the switch being installed, it is
recommended to keep the switch rack in a room with a stable temperature
and humidity. Please use an air-conditioner to cool it up in summer and a
heating system in winter. Too high a relative humidity will harm the effect
of insulation material, which may result in electric leakage. Sometimes it
may also change the mechanical properties of some materials and cause
metal corrosion. While in too low a relative humidity, the insulation spacer
may contract, resulting in loosed fastening screws. Besides, working in too
dry an environment will increase the danger of static electricity,
threatening the switch circuits. If the environment temperature is too high,
the reliability and lifespan of the switch will be affected, and the aging of
insulation material will be accelerated. The recommended working
temperature and humidity are listed in the following table:

Caution
The working environment temperature and humidity of the switch should
be measured at 1.5m above the floor and 0.4m in front of the rack,
without front or back protective panel on the rack.
