Operation Mode Selector
a). “UPS”: setting for conventional electrical appliance.
If you select this mode, the unit's input utility range will be 162~290VAC as normal home UPS.
If the utility is higher or lower than this range, the unit will transfer to inverter mode
automatically. And you can connect the computer systems or other precision home
equipment when you select this operation mode.
b). “INV.”: setting for energy saving
If you select this mode, the unit's input utility range will be extended to 90~280VAC. If the
utility is higher or lower than this range, the unit will transfer to inverter mode automatically.
So, you can connect the home equipments, such as light bulb, fluorescent tube, fan, or TV
on this mode.
Caution!!
If you select the “INV.” mode and connect the computer to the output of the unit,
the computer may reboot if the input voltage is too low to be accepted.
