1. The ambient air temperature does not exceed +40℃, the average temperature within 24 hours and not more than +35℃.The ambient air temperature is not lower than -5℃ .
2. Installation site altitude does not exceed 2000m
3. The relative humidity of the air no more than 50% when the maximum
temperature is +40℃ and at a lower temperature allows a higher relative
humidity, such as when temperature is 20℃ the relative humidity reaches 90%.
4. Special measures should betaken for condensation occassionally due to temperature changes.
For use to master control
