5-2-6 Wiring and Assembly of Communications Connector and MIL
Connector for Connector Terminals
Connect the communications cable to the Connector Terminal using the rectangular
communications connector provided with the Unit. The Connector
Terminals with MIL connectors are used to connect the external I/O. The wiring
and assembly methods of square communications connectors and MIL
connectors are described here.
The Connector Terminals with sensor connectors are used to connect the
external I/O cable connector. The cable connector wiring and assembly methods
are the same as for Sensor Terminals, so refer to 3-4-3 Cable Connector
Wiring and Assembly for details.
Wiring A CompoBus/S cable must be connected to a Connector Terminal after the
communications data (BD H, BD L), communications power supply (BS+,
BS–), and I/O power supply (G, V) lines are connected to the communications
connector (i.e., the connector on the cable end). I/O power is not supplied to
32-point Connector Terminals.
!Caution Be sure to turn OFF the Slave power supply and communications power supply
before connecting communications data, communications power supply,
or I/O power supply lines, and before attaching or detaching connectors. For
the connector, use the communications connector provided with the Connector
Terminal.
Use the following procedure to connect the communications data, communications
power supply, and I/O power supply lines to the connector.
1,2,3... 1. Remove sufficient insulation from the signal wires for a crimp terminal, and
twist the exposed wire strands together tightly.
If using VCTF cable, cover the severed end of the insulation with vinyl tape
or heat-shrinking tube.
Apply vinyl tape or heatshrinking
tube
2. After attaching a crimp terminal to the exposed signal wires, cover with vinyl
tape or heat-shrinking tube.
