5-3-1 Wiring to the Screwless Clamping Terminal Block
Using Ferrules
If you use ferrules, attach them to twisted wires.
Observe the application instructions for your ferrules for the wire stripping length when attaching fer-
rules.
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 listed in the following table.
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.
