Note

Note

  • The ambient temperature of the operating environment must not exceed 45°C at sea level when using the 1100W or 2000W power supplies.
  • The ambient temperature of the operating environment must not exceed 40°C at 1,500 meters.
  • The ambient temperature of the operating environment must not exceed 35°C at 3,000 meters.
  • The ambient temperature of the operating environment can be in the range of 0°C to 50°C at sea level to 3,000 meters when using 5720 models with the 715W power supply.
