The maximum ambient temperature cannot exceed 40, the minimum cannot be lower than 5, and the average temperature in 24 hours cannot be higher than 352. The height of the installation site should not be higher than 2000m3. When the maximum temperature reaches 40, the relative humidity of the installation site should not exceed 50%, when the temperature is the lowest temperature -5, the relative humidity is higher, for example: the temperature is 25, the relative humidity is 90%. Due to temperature changes, special measures must be taken to deal with occasional condensation on the surface of the product
