Connect all cable drain shields to a single-point cabinet ground bar. For conduit entries penetrating the enclosure wall, ensure threaded NPT connections achieve a minimum of 5 full threads of engagement to maintain physical strain relief and grounding continuity.\u003c\/p\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":53394629263669,"sku":"P0918EU","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/FBM241P0914TG2_930c9e41-93f3-4dea-baf9-5e7cdac06d3f.png?v=1787563466","url":"https:\/\/www.5gplc.com\/products\/foxboro-p0918eu-i-a-series-plc-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
