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.

 

△周围空气温度不高于+40℃,不低于-5℃。24h内平均温度不得高于+35℃。

△户内安装使用,使用地点的海拔高度不得超过 2000m

△周围空气相对湿度在最高温度为+40℃量不超过 50%,在较 低温度时允许有较大的相对湿度。{例如+20'℃时为 90% )应考虑到由于温度的变化可能会偶然产生凝露的影响。

△设备安装时与垂直面的倾斜度不超过 5%。

△设备安装时在无剧烈震动和冲击的地方,以及不足使电器元件受到腐蚀的场所。

△用户有特殊要求时可与制造厂协商解决。
