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