1.Ambient temperature: -5℃~+40℃, and the average value within 24h does not exceed +35℃
2.Altitude of the installation place does not exceed 2000m
3.Atmosphere condition: The relative humidity does not exceed 50% when it is at +40℃, it allowed relatively high humidity at the relatively low temperature, for example,the relative humidity reaches 90% when +20℃, and it should take special measurements when there produced the condensation on the product due to the temperature variation
4.It should be at the no explosion danger medium, and the medium without the gas that can not corrode the metal and damage the insulation as well as the places that without conductive dust
5.Grade of pollution: 3
6.Installation category:Ⅲ
7.Installation position: installed at the normal position, the gradient between the installation side and the vertical side does not exceed +5°,and without obvious vibration and impact
8.Protection grade: IP 20
