Operation during recovery from a power failure
• If a power failure or abnormal power input is resolved while the UPS supplies power, it returns to the
commercial power output status automatically. Charging the consumed battery starts.
• If a power failure or abnormal power input is resolved after the battery is discharged completely and
power output is stopped, the UPS restarts automatically and resumes power output. The expended
battery begins to charge.
