Wiring to connectors

(1) Precautions
• Connectors for external devices (A6CON ) must be crimped, pressed, or correctly soldered.
• Plug connectors for external devices (A6CON ) securely to the module and tighten the two screws.
• Use copper wires having temperature rating of 75°C or more for the connectors.
• Tighten the connector screws within the following specified torque range.
Connector screw (M2.6)
• To use the high-speed counter function (built-in I/O function) in 1-phase input, connect the pulse input cable
to A-phase line.
• Do not connect the module to the connector/terminal block converter module (A6TB ). If not, I/O signals of
the CPU module short, resulting in damage to the module or cables or malfunction due to poor connection.
• Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor connection.
To make the wiring comply with the EMC and Low Voltage Directives, Page 383, Appendix 7.
Even when compliance with the EMC Directive and Low Voltage Directives is not required, configuring the system that
complies with the EMC Directive may reduce external noise.
