Explosion-proof electric hoist control box working conditions:
1, the ambient air temperature is -20 ℃ ~ +40 ℃.
2, the relative humidity in the air: the lowest average humidity is 90%, and the average minimum monthly temperature is 25 ℃, and taking into account due to temperature changes on the surface of the product of the frost.
3, the work field must be no place severe shaking and vibration.
4, in no danger of explosion in the medium, and medium without corrosion and damage to the insulator of gas and dust (including conductive dust).
5, not more than 2500 meters of altitude.
6, in the absence of snow or rain (rain local control box except).
