The maximum ambient temperature should not exceed 40, and the minimum should not be below 5. The average temperature within 24 hours should not exceed 35.2. The installation site's altitude should not exceed 2000m.3. When the maximum temperature reaches 40, the relative humidity at the installation site should not exceed 50%. When the temperature is at the lowest point of 5, the relative humidity is higher, for example, at a temperature of 25, the relative humidity would be 90%. Due to temperature changes, special measures should be taken to handle occasional condensation on the surface of the product.
