Temperature and Humidity

Although the switch is designed to use 3 fans, the site should still 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 in cold weather, use of heaters is recommended.
The recommended temperature and humidity are shown below:

15 ~ 30°C
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 continued operation
and an annual cumulative total of less than 15 days. Excessive operating conditions refers to
the ambient temperature and relative humidity value that may occur during an air-conditioning
system failure - normal operating conditions should be recovered within 5 hours.
