5.4.1 Wiring precautions
External wiring that is less likely to be affected by noise is one of the conditions for a highly reliable system that fully
utilizes the Q64TCN.
This section describes wiring precautions.
• Use separate cables for the AC control circuit and the Q64TCN's external I/O signals to avoid influence of
AC side surges and induction.
• Do not locate external wires near the main circuit line, high-voltage circuit lines, and load circuit lines of
devices other than programmable controllers such as an inverter. Also, do not bunch external wires with
these lines. Otherwise, the external wires are more likely to be affected by noise, surges, and induction.
• Ground shielded cables at one end on the programmable controller side. However, depending on the
external noise condition, it should be grounded on the other side.
• To ensure that this product maintains EMC and Low Voltage Directives, please refer to the manual included
with the CPU module or base unit.
