(3) Output voltage and Input voltage
There are AC100V type UPS and AC200V type UPS at the specification of the input and the output
voltage. In case of using the AC100V type UPS, two transformers (AC200V to AC100V and AC100V to
AC200V) should be connected to the input and the output of UPS.
In case of AC100V input

in the power failure.（not through the UPS）
(4) Other notice
Use the sine wave voltage output type.
It is possible to use the UPS type which is normally supplied from AC line directly and supplied through the
inverter only in the power failure, provided that the switching time from AC line to the inverter line is less
than 10msec. (General used UPS type is supplied through the inverter not only in the power failure but in
the normal condition.)
