Package List: 1 x Dual Power Automatic Transfer Switch Note: 1. 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.
