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.

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.

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.

3.

Leave the tip of the wire created by twisting the shield exposed and cover
the remaining section with a heat-shrinking tube.

4.

Remove enough of the cover from the signal lines to allow the crimp termi-
nals to be connected, taking care not to damage the signal lines. Damage
to the signal lines could cause the cable to break.
