External Wiring Connections
• Refer to the wiring connection diagram to connect them.
• All wiring must be over the specified 1.5
mm
2
and be shielded.
• When using shielded wiring, all shielded wires not indicated on the wiring connection diagram must be
grounded to the frame.
1. Twisted cables must be used for the actuator wiring.
IMPORTANT
After connecting the wiring, the resistance between A-B must be 3.5 ~ 4.5

.
2. The cables for the magnetic speed sensor must be "shielded wires," and the shielded part must be con-
nected to terminal D as well.
IMPORTANT
If this shielded part is grounded to the engine or not grounded, a distorted speed signal may
be entered and cause problems such as hunting, so be sure to ground it.
3. Be careful not to reverse the polarity of the battery connected to terminals E and F, and be sure to install a
10 A fuse between the positive (+) battery terminal and terminal F.
IMPORTANT
After connecting them, be sure to check whether the voltage between the terminals is DC 24V
(±4 V). Also, ground terminal E to the frame. (Wiring connection no.10)
4. Connect a 5 kW resistor externally as shown in the picture to enable the engine speed to be fine-tuned
within a range of around "set speed ± 210 Hz."
5. When using a 12V battery or an actuator with a current consumption over 5 A, use a jumper to connect
terminals G and H.
6. A selection switch for switching between the crank speed mode and run speed mode.
7. The droop mode selection switch.
IMPORTANT
ON (connected): droop mode / OFF (disconnected): isochronous mode
8. Connects the signal coming from the auxiliary device used in the parallel operating system to terminal N.
IMPORTANT
Use shielded wires.
9. Accessory power supply: Terminal P, which supplies rated power of +10[V], 20[mA], can be used as a
power supply for external auxiliary devices and applied in a variety of different ways.
IMPORTANT
However, it should only be used within the range of the rated capacity. Be careful to avoid
short circuits, and in the event that the capacity is exceeded, it may cause critical damage to
the controller.
