Set to O : Vo fluctuates according
to the input voltage
Set to
Output frequency [Hz]
: Vo is automatically set between the following values
according to the input voltage when the power is
turned on.
200V class: 200 to 230Vac
400V
class: 380 to 460Vac
Set to c' : Vo is set with lu L ,_, II.
* Even if lw L ,_, :I is set higher than the input voltage, the output voltage will not be higher than the input
voltage.
* Even if ~lw_L_w~ll is set when J,_, L 5 L I is set to I , it will be ignored.
