Wired Controller Link Unit Wiring
Section 3-3
Terminal Block Connections
Not Unit a Relay Terminal Block
Note Use the recommended crimp terminals when connecting the cable’s signal
lines or shield line to the terminal blocks. Short circuits can damage the Units.
Using a Relay Terminal Block
Note
1.
Mounting and dismounting during communications is not possible for Re-
lay Terminal Blocks connected to the nodes at the ends of the network (i.e.:
the nodes with terminating resistance).
2.
Use the recommended crimp terminals when connecting the cable’s signal
lines or shield line to the terminal blocks. Short circuits can damage the
Units.
3-3-2
Connecting the Communications Cables
Use crimp terminals when connecting communications cables to a Controller
Link Unit. Use the following procedure to connect communications cables to a
terminal block.
1,2,3...
1.
Peel back the cover of the cable for about 50 mm without scratching the
mesh of the shield. Do not peel too much because it may cause a short-
circuit.
2.
Twist the mesh of the shield to form a line.
