Normal working condition and mounting conditions

Ambient temperature: -5°C~+40°C 
2. Altitude: ≤2000m;
3.When the ambient air temperature is +40°C, the relative humidity of the air shall not be higher than 50%; a higher relative humidity is allowed at a lower temperature; for example, for the wettest month, the maximum relative humidity averaged shall be 90% while the lowest temperature averaged in that month +20°C, and special measures shall be taken for the condensation occasionally produced due to temperature change.
4.Pollution degree: 3
5.The ambient air is not significantly polluted by dust, smoke, corrosive and/or flammable gases, vapours or salt.0A 1600
