Ensure field power supplies are clean, well-regulated, and share a common reference ground to prevent channel crosstalk or erratic switching thresholds.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1.5rem;\"\u003eAlways verify that the positioning alignment keys on the matching Input Termination Assembly (IOTA) block match the module configuration.
