1.Ambient temperature:-5℃~+40℃, average value within 24h does not exceed +35℃
2.Height of altitude:does not exceed 2000m
3.Atmosphere: when highest temperature is +40℃, the relative humidity does not exceed 50%; it allowed the relatively high humidity when it is under the relatively low temperature, for example, it reaches 90% when +20℃.It should take special measurements if there produced condensation that is due to the temperature variation.
4.Grade of pollution:3
5.Installation category:Ⅲ
6.Position of installation: the gradient between the installation side of relay and the vertical side is not more than ±5°
7.Impact and vibration: product should be installed and used at the places of no obvious shake,impact and vibration.
8.Installation mode:
JRS2-12.5,25,32,45,80 has three kinds of installation mode: combination installation, screw installation,35mm standard rail installation
JRS2-63,135,150,180,400,630 has two kinds of installation mode: screw installation, 35mm standard rail installation
