2.5 Connect AC Input Cables and Loads
Connect the AC input cables and loads to the receptacles as shown below.
2.6 AC Input Voltage Range Selector
A.
“NARROW” setting:
Set the selector to “NARROW” when connected with loads which are more
sensitive on voltage range. With this setting, the inverter is more sensitive
to the voltage disturbance on the AC input and the input voltage range is set
at 170~280VAC while output voltage follows input voltage.
B.
“WIDE” setting:
Set the selector to “WIDE” when connected with loads which are less
sensitive on voltage range (e.g. light bulb, fan, fluorescent tube, or TV). With
this setting, the inverter’s input voltage range is extended to 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 which are sensitive to transfer time (e.g. computer) might
result in power interruption.
