1. The ambient air temperature is - 5 ℃ ~ + 40 ℃, and the average value of 24 hours is not more than + 35 ℃;
2. The altitude of the installation site shall not exceed 2000m;
3. The relative humidity of the air shall not exceed 50% when the maximum temperature is + 40 ℃; the relative humidity may be higher when the temperature is lower, and the monthly average minimum temperature of the wettest month shall not exceed + 25 ℃, and the monthly average maximum relative humidity of the month shall not exceed 90%, and condensation on the product surface due to temperature change shall be considered; pollution level 3;
4. The temperature during transportation and storage can be between - 25 ℃ and + 55 ℃, and it can reach + 70 ℃ in a short time (no more than 24 hours).
