The maximum ambient temperature should not exceed 40, the minimum should not be lower than 5, and the average temperature within 24 hours should not be higher than 35.2. The altitude of the installation site should not be higher than 2000meter.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 of 5, the relative humidity is higher, for example, if the temperature is 25, the relative humidity is 90%. Special measures should be taken to deal with occasional condensation on product surfaces due to temperature changes.
