Normal operational conditions and installation conditions
1 Temperater: no higher than +40ºC,and no lower than -5ºC,and the day average temperature no higher than +35ºC.
2 Altitude: no higher than 2000m
3 The relative humidity: no more than 50%,when temperature is +40ºC.The product can withstand higher humidity under lower temperature,for instance,when it at +20ºC,the production can withstand 90% relative humidity.
The condensation that happened because of temperature changes should be taken care.
And Installation location should have no exploresion danger, and no gas and conductive dust which can cause corrosion and insulation damage.
4 Class of pollution: 3 Calss
5 Installation type:III, IV.
