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 2000m3. 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. Package List 1 x Automatic Transfer Switch 1 x User Manual
