2.3 Wiring
(1) Wire the shielded twisted pair cable after stripping its sheath to make its
cables loose.
Also, protect the shielded cable of the shielded twisted pair cable to
ensure that it will not make contact with the conductive area.
Strip the signal wires as shown below. If too much of the wire is
stripped, a short circuit may occur with neighboring wires.
If not enough of the wire is stripped, wires may become loose and fall out.
Twist the stripped end of wires to prevent them from fraying. Do not solder it.
Use appropriate crimp terminals (ferrules, blade terminals, etc.) for these terminal blocks as
necessary.
