This section describes how to connect wires to the screwless clamping terminal blocks, 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.
Wiring Terminals
The terminals to be wired are as follows.
• I/O power supply terminals
• I/O terminals
Applicable Wires
You can connect twisted wires, solid wires, or ferrules attached to twisted wires to the screwless
clamping terminal block. The applicable wire dimensions and preparation methods are given below.
l
Dimensions of Wires Connected to the Terminal Block
The dimensions of wires that you can connect into the terminal holes of the screwless clamping
terminal block are as in the figure below.
Process the applicable wires that are specified in the following description to apply the dimensions.
1.6 mm max. (Terminals other than ground terminals)
