A.3.2 Humidity, Temperature, and Cleanness
This section describes the requirements for the humidity, temperature, and cleanness of the
equipment room. To ensure the stability and life cycle of the USG and its components, check
that the equipment room meets the requirements.
Ensure that there is no explosive, conductive, magnetic, or corrosive dust or debris in the
equipment room. Dust that settle on the device may cause electrostatic adsorption, resulting in
poor contact of the metal socket connectors and metal contacts. This shortens the life cycle of
the device and causes faults.
In addition to dust and debris, toxic gases, such as SO
