● Altitude:≤2000m
● Ambient air temperature:-5℃~+40℃, average temperature of 24 hours must below+35℃
● Relative humidity: the maximum temperature of 40 degrees, the air relative humidity not exceed 50%, at a lower temperature can allow for a higher relative humidity. The wettest month’s average lowest temperature must be below 25℃,the max relative humidity of that month should not exceed 90%. If humidity changes as a result of occasional gel generated, should eliminate it.
● Installation position: The installation degree of the tilt and vertical plane should not exceed 5°
● In a non-explosive hazardous medium, and there is no place in the medium that is sufficient to corrode metals and destroy insulation gases and conductor dust.
● Where there is rain and snow protection and there is no steam.
