Precautions for Correct Use
If you use DIN Track Insulation Spacers to install a CPU Rack, the height will be increased by
approximately 10 mm. Make sure that the CPU Rack and connecting cables do not come into
contact with other devices.
For information on wiring the built-in EtherCAT port, refer to the NJ/NX-series CPU Unit Built-in Ether-
CAT Port User’s Manual (Cat. No. W505).
For information on wiring the built-in EtherNet/IP port, refer to the NJ/NX-series CPU Unit Built-in Ether-
Net/IP Port User’s Manual (Cat. No. W506).
This section describes how to connect wires to the screwless clamping terminal block on the CPU 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.
Use the correct wiring parts and tools when you wire the system. Otherwise, cables may be
disconnected to cause short-circuit or wire breakage.
