In addition, salt, acid and sulfide in the air are also harmful to the switch. Such
harmful gases will aggravate metal corrosion and the aging of some parts. The site
should avoid harmful gases, such as SO

2.1.1.2 Temperature and Humidity
The switch installation site should maintain a desirable temperature and humidity.
High-humidity conditions can cause electrical resistance degradation or even electric
leakage, degradation of mechanical properties and corrosion of internal components.
Extreme low relative humidity may cause the insulation spacer to contract, making the
fastening screw insecure. Furthermore, in dry environments, static electricity is liable to
be produced and cause harm to internal circuits. Temperature extremes can cause
reduced reliability and premature aging of insulation materials, thus reducing the switch's
working lifespan. In the hot summer, it is recommended to use air-conditioners to cool
down the site. And the cold winter, it is recommenced to use heaters.
The recommended temperature and humidity are shown below:

Caution!
A sample of ambient temperature and humidity should be taken at 1.5m above the
floor and 0.4m in front of the switch rack, with no protective panel covering the front and
rear of the rack. Short term working conditions refer to a maximum of 48 hours of
