5.6 Auto Restart
When the mains power failure, the UPS draws power from the battery to supply the load until the batteries are
depleted, then the UPS will shut down.
The UPS will automatically restart and recover output power supply:
• After the mains power is restored.
• The UPS Auto Restart function is enabled.
• After the Auto Restart is delayed (default: 10s). During the Auto Restart delay, the UPS will charge the
battery to provide a safety margin for equipment shutdown if input power fails again.
If the Auto Restart function is disabled, you can restart the UPS manually by pressing the power button.
