3-phase 200/220/240V type and single-phase 100/110/120V type can be changed over by changing the power
source cable and changing over of the jumper.
Changeover of jumper

The machine uses the following three fuses:
Change over the jumper in accordance with the voltage
used.
For the change of the connection of power source cable,
refer to the item (Instruction manual (2)) of "Connecting
