Attention matter	1. The analog indication input signals are all taken from the auxiliary contacts of the corresponding primary components in the switchgear, which are passive contact types. 2. The heater and fan control outlets of the temperature and humidity control section are passive outputs; 3. The locking control outlet of the high-voltage live part is a passive output.
use condition	·Indoor use with good ventilation;·Altitude: ≤ 2km; ·Environmental temperature: -20 ℃ to 80 ℃;·Relative humidity: ≤ 95%; ·Atmospheric pressure: 80-110kPa; ·The surrounding medium is free of conductive dust, corrosive gases that can damage metal or insulation, mold, etc.

Note:
Please choose the appropriate product based on the installation space of the cabinet and the functional requirements;
If there is a temperature and humidity function, please provide the power of the heater.
