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 temperature control module.
This section describes wiring precautions.
• Use separate cables for the AC control circuit and the temperature control module'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, refer to the following.
