Normal use environment

The ambient air temperature is not higher than +45℃, not lower than -15℃, and its average temperature within 24 hours is not higher than +35℃.

Atmospheric conditions, the air is clean, the relative humidity does not exceed 50% when the highest temperature is +40℃, and higher relative humidity is allowed at lower temperatures, such as 90% at +20℃, but temperature changes should be taken into consideration. It is possible to occasionally produce moderate condensation.

Indoor installation, the altitude does not exceed 1000m.

There is no fire, explosion hazard, severe pollution, chemical corrosion and severe vibration.

If the above conditions of use cannot be met, or special requirements, the user and the manufacturer need to negotiate and resolve.
