The maximum peripheral temperature should not exceed 40, the minimum should not be lower than 5, and the average temperature in 24 hours should not be higher than 35.2. The altitude of the installation site should not be higher than 2000m. 3. When the maximum temperature reaches 40, the relative humidity of the installation site should not be more than 50%. When the temperature is a minimum of 5, the relative humidity is higher, e.g., when the temperature is 25, the relative humidity is 90%. Due to temperature changes, special measures should be taken to deal with occasional condensation on the product surface.
