Prepare a cable and process terminals
Prepare four-core cable.
●Cross-section area:
3.5 to 5.5 mm

Process the terminals to
be connected to the
machine.
Remove the front
right side cover

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.
5
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.

●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
2.8 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).

●Insert the special driver deep enough to
open the fixing bracket inside the cable
insertion slot.
●Make sure that the PE wire on the plant
side is connected to ground.

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: Allen wrench (4 mm), 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
6
●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.
1. 480 V
2. 420 V
3. 400 V
4. 380 V
5. 220 V
6. 200 V
5
Connect U, V, and W to the same voltage taps
(Ex. for AC400 V to 200 V)
●Use the attached special driver to
connect each cable.
Then, insert the ferrules fully.
