When the VCTF cable is connected to an SRS1-T Terminal-block Terminator,
use crimp terminals on each of the BD H and BD L signal wires, and connect
them to each terminal. The signal wires can be connected to any of the terminals.
Note 1. Do not connect both signal wires to a single terminal.
2. When connecting the communications power supply using Special Flat
Cable or 4-conductor VCTF cable, insulate the BD+ and BS– power supply
cables.
Tighten the terminal screws to the specified tightening torque (0.3 to
0.5 N⋅m).
3. When connecting Terminal-block Terminators to VCTF cables, use the
same crimp terminals as those used to connect the communications cables
to the Slaves. (Refer to 3-4 Master/Slave Connecting Cables.)
Shield Terminators When using 4-conductor VCTF cable, terminators can be connected by connecting
an SRS2-1 Shield Terminator to the T-joint.
Note The SRS2-1 Shield Connector has a male plug. Connect it to the female
socket connector of the T-joint.

3-4-1 Crimp Terminal Installation
This section describes the methods used for connecting communications
cables to each device and installing connectors on the Connector Terminal
and Sensor Terminal cables.
Attach crimp terminals to the ends of the communications cable when connecting
the cable to a Master, Slave, Terminal-block Terminator, or commercially
available terminal block.
!Caution Do not connect bare signal wires to the terminals since the wires could short
and damage the Unit to which they are connected.
Note Do not strip too much insulation from the wires when preparing the cable for
the crimp terminals. Cover the shaft of the terminal connector and the end of
the wire with electrical tape or heat-shrinking tube.
Master or Slave When connecting communications cable (VCTF cable or Special Flat Cable)
to a Master or Slave, attach an M3 crimp terminal like those shown below to
each signal wire.
