If a top outlet fan is configured, check the fan running status after enabling
this parameter.
If the mains is not functioning normally, the UPS will transfer to battery
mode. When batteries reach the EOD threshold, the bypass is disabled, and

regardless of whether the parameter is Enable or Disable.
Specifies whether to automatically clear the alarm and restart the power
module when the rectifier or inverter shuts down due to a bus overvoltage
alarm. If Bus overvoltage recovery is set to Enable, the bus overvoltage
alarm is automatically cleared, and the rectifier and inverter automatically
start when the bus voltage recovers (less than 420 V) within Bus overvolt.
recovery time. When Bus overvoltage recovery is set to Disable, the bus
overvoltage alarm cannot be automatically cleared, and the rectifier and
inverter cannot automatically start. The default value is Enable.
If Bus overvoltage recovery is set to Enable, the bus overvoltage alarm is
automatically cleared, and the rectifier and inverter automatically start
when the bus voltage recovers (less than 420 V) within Bus overvolt.
