Verify thermocouple polarity before termination because reversed wiring affects temperature signal interpretation.\u003c\/p\u003e\n\u003cp\u003eUse shielded thermocouple extension wiring where required by the installation environment. Connect cable shields according to cabinet grounding practices and avoid routing thermocouple cables parallel to high-current power conductors to reduce electromagnetic interference.\u003c\/p\u003e\n\u003cp\u003eConfirm terminal tightness, connector seating, and compatibility with the associated VTCC input interface before system energization. Follow GE Mark VIe hardware installation documentation for cabinet layout, grounding, and signal segregation requirements.\u003c\/p\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":44357575475288,"sku":"IS230TVBAH4A","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/IS230TVBAH4A.jpg?v=1783678837","url":"https:\/\/www.industriaxplc.com\/products\/ge-is230tvbah4a-thermocouple-input-terminal-board","provider":"IndustriaX Limited","version":"1.0","type":"link"}
