Ambient air temperature not higher than +40℃, not lower than -5℃.The average temperature within 24h shall not be higher than +35℃.
Rural indoor installation and use, the altitude of the use site shall not exceed 2000m
Ambient air relative humidity at the highest temperature of +40℃ the volume does not exceed 50%, at the lower temperature allows for greater relative humidity.{for example, 90% at +20' c] the effect of condensation may occur by chance due to temperature changes should be taken into account.
The inclination of the vertical plane during installation should not exceed 5%.
Delta equipment should be installed without severe vibration and shock, and in areas where insufficient corrosion of electrical components can occur.
Delta users have special requirements can be negotiated with the manufacturer to solve.
