ECO Mode

After the UPS is manually set as ECO mode via the LCD, the UPS will work in Bypass mode
if bypass input voltage and frequency are within ±10% of the rated voltage and ±3Hz of the
rated frequency respectively. Otherwise, the UPS will run in On-Line mode. During ECO
mode, the UPS's tri-color LED illuminates green and the text 'ECO' appears in the upper
right corner of the LCD screen.
