Proper earth‑ground continuity reduces noise coupling into Profinet and EtherNet\/IP deterministic networks, preventing transient disturbances on shielded twisted‑pair cabling. The mechanical stability of the 35 mm DIN rail mount supports consistent grounding performance under vibration.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the terminal block accept both solid and stranded conductors?\u003c\/strong\u003e A: Yes.
