䕔 Detail Connection Diagram
[Connection by Terminal Block or Joint]

* The user must provide relay terminals. Also, connect a terminal resistor (220

:, 1/4 W) between the SGA and

SGB terminals.
Do not ground the end of the main communication line, but terminate it using a terminal block or leave the end
open without any termination.

Preparation of Communication Main Line

[Wiring by Connector]

[1] Strip the sheath of a double shielded twisted-pair cable by

approx. 15 to 20 mm.

[2] Twist the shield wires and solder them onto vinyl wires of

AWG22 (outer diameter 1.35 to 1.6 mm) or equivalent.

[3] Place a cable protection tube over the cable.
[4] Insert the four wires into the cable insertion holes in the

connector (SDA, SDB, GND, FG) without stripping the core
sheath.

[5] With the cable inserted in the press-fit cable housing, apply

pressure from above to pressure-weld the core wires.

[6] Heat-treat the cable protection tube.

If installing a terminal block is
difficult or any other wiring
limitation applies, connect the
cable directly using a joint, instead
of using a terminal block.
Connect each wire using a round
crimp terminal with a screw/nut,
and then wrap an insulation tape
around the connection point.
