6 INSTALLATION AND WIRING
6.9 Wiring of I/O Module and External Device
Precautions
• Use bar solderless terminals for wiring to the terminal block. If a stripped wire is inserted into a wire insertion opening as-is,
the wire cannot be securely clamped.
• Use a crimping tool to connect a bar solderless terminal to a wire. ( Page 136 Applicable solderless terminal)
• When inserting a bar solderless terminal, check that the size of the terminal and its insertion direction are correct to prevent
the terminal from getting stuck in or the terminal block damage. When using a bar solderless terminal other than the
applicable solderless terminals, check that for its size, the cross-sectional shape of the terminal after processing (1) is
smaller than the size mentioned below, even including an error in processing. For the correct terminal insertion direction,
refer to the figure below.
For details on the finish shape of a bar solderless terminal including an error in processing, contact the
manufacturers of the bar solderless terminal and the bar solderless terminal tool.
