The maximum ambient temperature shall not exceed 40 , the minimum temperature shall not be lower than 5 , and the average temperature within 24 hours shall 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 exceed 50%. When the temperature is the lowest temperature 5, the relative humidity is higher, for example, 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 surface of the product.
