1.Amblent air temperature
a. The upper limit of ambient air temperature does not exceed +40*C:b. The lower limit of the ambient air temperature is not less than -5'c (it can also be -10'C or -25°c, but it should bestated to the manufacturer when ordering)
2.Altitude
The elevation of the installation site does not exceed 2000m.
3.Atmospheric condition
The relative humidity of the atmosphere does not exceed 50% at the maximum temperature of +40'C.The relative humidity can be higher at lower temperatures, and the monthly average maximum relative humidity carbe 9% when the monthly average minimum temperature is +25'C in the wettest month, and the condensation on thesurface ofthe product due to temperature changes should be considered.
