[Connection by Terminal Block or Joint]
* The user must provide relay terminals. Also, connect a terminal resistor (220
Ω, 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.

Producing a communication trunk
[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.
