Using Ferrules
If you use ferrules, attach the twisted wires to them.
Observe the application instructions for your ferrules for the wire stripping length when attaching
ferrules.
Precautions for Correct Use
Always use plated one-pin ferrules. Do not use unplated ferrules or two-pin ferrules.
The applicable ferrules, wires, and crimping tools are given in the following table.

and cannot be used in the screwless clamping terminal block.
When you use any ferrules other than those in the above table, crimp them to the twisted wires so
that the following processed dimensions are achieved.
