NX-series EtherCAT Coupler Unit User’s Manual (W519)
This section describes how to connect wires to the screwless clamping terminal block on the EtherCAT
Coupler Unit, the installation and removing methods, and functions for preventing incorrect attachment.
You can connect ferrules that are attached to the twisted wires to the screwless clamping terminal
block. You can also connect the twisted wires or the solid wires to the screwless clamping terminal
block. If you connect the ferrules, all you need to do to connect the wires is to insert the ferrules into the
terminal holes.
The wires that you can connect to the screwless clamping terminal block are twisted wires, solid wires,
and ferrules that are attached to the twisted wires. The following section describes the dimensions and
processed methods for applicable wires.
Dimensions of Wires Connected to the Terminal Block
The dimensions of wires that you can connect into the terminal holes of the screwless clamping ter-
minal block are as in the figure below.
Process the applicable wires that are specified in the following description to apply the dimensions.
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 fer-
rules.
Always use one-pin ferrules. Do not use two-pin ferrules.
The applicable ferrules, wires, and crimping tools are listed in the following table.
