Backup power features
The unit’s 120V AC outlets are permanently backed up by the internal battery. To activate the
AC outlets, turn on the unit using the power button. During a power outage or other utility
problem (such as brownouts and over-voltages), the Backup Power System will keep your
AC-powered products, office equipment, or small household appliances powered, depending
on the power draw of your application. When utility power is restored, the unit automatically
recharges its internal battery.
Important:
When connected to utility power, the unit automatically provides AC power from its
internal battery when the utility voltage falls outside the 108-127V AC range. The emergency
LED light turns on automatically to illuminate the rear AC outlets.
