Connection and Wiring
 Connecting the control cable and wiring
1 Align the protrusion in the cable connector with the notch in the
control port.
2 Tighten the connector screw by turning it clockwise.
3 Connect the wires according to the usage.
z When the I/O terminals are not used
z NPN wiring
z PNP wiring
 Connecting the Ethernet cable
1 Align the protrusion in the cable connector with the notch in the
Ethernet port and connect the cable to the main unit.
2 Tighten the connector screw by turning it clockwise.
The screw tightening torque should be within the range between 0.8 and
1.0 N·m.
 Connecting the USB cable
1 Confirm the orientation and insert the connector straight so that it is
not tilted.
Screw tightening torque:
1.5 to 2.0 N·m

• Be sure to turn power off before attempting to connect or disconnect the
control cable.
• Insert the connector straight so that it is not tilted and then tighten it
securely. Under-tightening can lead to a loose connector due to
vibrations, resulting in poor contact.
* After tightening it as much as possible by hand, tighten it further
approximately 90° - 120° using a tool such as pliers.
• Insulate unused wires individually.
• Be sure to provide Class D ground for the FG wire.
• The shield and FG wires of the control cable and the shield wire of the
Ethernet cable are electrically connected via the main unit housing. Be
sure to provide them with a common ground.
• When connecting the connector, insert it so that it does not tilt, and then
push in and tighten the connector securely. Under-tightening can lead to a
loose connector due to vibrations, resulting in poor contact.
• After tightening it as much as possible by hand, tighten it further
approximately 5° - 10° using a tool such as pliers.
• Do not bend the base of the Ethernet cable connector repeatedly. It may
cause connection failure.
When connecting the connector, insert it straight so it does not tilt.
Otherwise, the connector pin may be damaged.
