Relative humidity: no more than 85%;
Atmospheric pressure: 80kPa~106kPa;
There is no strong vibration around it.
Direct radiation without direct sunlight or other heat sources;
There is no strong air flow around it: when the surrounding air needs to be forced to flow, the air flow should not be directly blown to the box.
There is no strong electromagnetic field around it.
There is no high concentration of dust and corrosive substance around it.
The second is power supply / water supply conditions:
