Tool used: Phillips screwdriver (No.2), special driver (provided)
Process the terminals to
be connected to the
machine.
Confirm secured insertions
Remove the special driver.
(The fixing bracket inside the cable insertion
slot closes)
Pull on the cable with a force of 50 N and
ensure that it is firmly-secured.
Insert the cable
Special driver (provided)
Insert the tip of cable
all the way to the end.
●Insert the sleeve terminals until their insulating
coatings go inside the terminal block.
●Connect the PE wire (green/yellow) first and then
connect the terminals in the order of L1→L2→L3.

Pass the cable through cable clamps A and B, in that order
Cable
clamp B
●Recommended cable external dimensions:
13.5 to 18mm
●If you have trouble passing the cable through
Cable clamp A, loosen the clamp by turning it
counterclockwise.
●If you have trouble passing the cable through
Cable clamp B, pass the cable after removing the
mounting bolt and then bolt it again.
After passing the cable through Cable clamp A,
secure it by turning the clamp clockwise.
Pull on the cable with a force of 100 N and
ensure that the cable is firmly-secured.

Check the following conditions before
turning on the power
Ordinary use
power source
3-phase AC 200/220 ±10 V
380/400/420/480 ±20 V
Frequency
50/60 Hz ±5 %
Rating capacity
2.5 kVA
The primary power should be supplied from power-supply
facilities controlled inside your plant, rather than establishing
a direct connection with the public low-voltage power
distribution system (commercial power).

1
Change the voltage of the primary power
supply
(The primary power supply voltage of the transformer can
be changed to any of the following voltages)
●Adjust it to the voltage of power supply.
Tool used: Phillips screwdriver (No.2), special driver (provided)
●Before using 290 V AC or higher (any tap equal to or
higher than 380 V AC), ensure that the voltage between
a ground and each phase is 290 V AC or lower and that
star connection is used on the feeding side, with the N
(neutral) terminal connected to the ground.
Adjust the difference in voltage between the primary power supply and the machine, if any.
Attach the cover, and relabel the numerical section of the supply voltage
label

●The label indicates the power
supply voltage supplied to the
machine.
When changing the power supply
voltage, purchase a new label and
relabel it.
In that case, align ▼ with the
numeric value on the supply voltage
label that corresponds to the power
supply voltage after the change.
