Setup and Wiring
Align the cable connector with the socket on the T-branch Tap as shown in the following diagram and
fully insert the connector into the socket. Tighten the set screws to secure the connection. Tighten
the screws to a torque of 0.3 N·m.
Note To avoid damaging the cable or breaking wires, do not pull on the cable or bend it too sharply
when connecting it to the T-branch Tap. Also, never place heavy objects on top of the cable.
3-2-4 Connecting Terminating Resistors
Terminating resistors must be connected at each end of the trunk line. Use the methods described
here to connect the Terminating Resistors.
● T-branch Tap Terminating Resistor
A Terminating Resistor is included with the T-branch Tap. Insert the Terminating Resistor into the T-
branch Tap as shown in the following diagram. The Terminating Resistor can face in either direction.
● Terminal-block Terminating Resistor
A Terminating Resistor is built into the Terminal-block Terminating Resistor. To connect the cable to
the Terminating Resistor, attach standard M3 crimp terminals to the signal wires and securely screw
the terminals to the Terminal-block Terminating Resistor. Tighten to a torque of 0.5 N·m.
