Connecting Wired Systems
Section 2-1
2-1
Connecting Wired Systems
This section describes the methods for wiring network communications cables
to the Controller Link Support Board (3G8F7-CLK23-E and 3G8F7-CLK21-
EV1).
2-1-1
Devices Required for Connection
The Wired Controller Link System uses the shielded twisted-pair cable speci-
fied below.
Note
1. Be sure to use the communications cable described above.
2. If another communications cable is used, normal operation cannot be as-
sured.
3. For manufacturers of the specified cable, refer to the appendix,
Standard
Models
.
2-1-2
Communications Cable
Wire the communications cable to connect identical signals.
Note
1. Use the cable specified for the communications cable.
2. Keep communications cable separated from power lines or a high-tension
lines to prevent influences from electronic noise.
3. Ground the shield line of the communications cable at one end of the net-
work. Do not ground the shield at both ends.
4. Do not connect the shield cable of the communications cable to a ground
that is also being used for power-system devices, such as inverters.
5. Turn ON the terminating resistance switch at the nodes at both ends of the
network to connect terminating resistance. Turn OFF the terminating resis-
tance switch at all nodes.
6. Do not run wiring outdoors. If outdoor wiring is necessary, take protection
measures against lightning, such as underground wiring or wiring inside
pipes.
7. The minimum length of the communications cable between nodes is 1 m.
Prepare the communications cables at a length of 1 m or more.
8. Use the multidrop method for connecting nodes. Normal communications
will not be possible with T branches.
9. Terminals for the same signal on the connector are connected internally in
the Controller Link Support Board.
10. Although this section discusses wiring Controller Link Support Boards
only, a Controller Link Unit could take the place of any Board and can be
connected in the same fashion as a Board.
