To prevent measurement errors during rapid ambient fluctuations, avoid mounting the box directly adjacent to heat sources or in areas experiencing severe draft currents. Unshielded thermocouple wires are highly susceptible to electromagnetic coupling; always maintain proper isolation from high-voltage variable frequency drive (VFD) cabling and use shielded thermocouple cables where possible.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1.5rem;\"\u003eWhen configuring the module within TwinCAT System Manager, navigate to the CoE (CAN over EtherCAT) online directory (specifically index 0x80n0) to select the correct thermocouple curve matching your physical sensor. By default, the module is configured for Type K thermocouples.
