System designers must maintain adequate ventilation space and ensure that cabinet temperatures remain strictly below 60 degC to prevent premature degradation of the diagnostic circuits. If transmitters are powered externally, the system ground reference must be carefully configured to prevent ground loop noise from corrupting safe signal values.\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eDuring commissioning, ensure all unused channels are disabled or configured with appropriate dummy resistors in Safety Builder to suppress open-loop error codes.
