AC input voltage range selector
“NARROW” setting:
Configure LCD to “NARROW” when connected to loads that are more sensitive on voltage
range. With this setting, the inverter is more sensitive to the voltage disturbance on the AC
input and input voltage range is set at 170~280VAC while output voltage follows input voltage.
“WIDE” setting:
Configure LCD to “WIDE” when connected to loads that are less sensitive on voltage range
(e. g. light bulb, fan, fluorescent tube, or TV ). With this setting, the input voltage range
is set at 90~280VAC while output voltage follows input voltage.
Please note that the inverter’s transfer time switching from Line Mode to Backup Mode
gets longer as the input voltage gets low. Under the circumstance, connecting the
inverter with loads (e.g. computer) which are sensitive to transfer time might result in
power interruption.
Connect AC input Cables and Loads
Connect the AC input cables and loads to the receptacles as shown below. Plug in the AC
input power cord to the wall outlet. The unit will automatically charge the connected external
battery even though the unit is off.
The user may connect the batteries in parallel in order to increase the total battery capacity
without changing the battery voltage. The example below shows parallel connection of
multiple 12VDC batteries. While the total capacity is times by the number of battery, the
terminal voltage remains 12VDC (only for 12VDC model).
