Connect protective earth grounding according to site electrical standards before applying auxiliary power.\u003c\/p\u003e\n\u003cp\u003eUse shielded cables for sensitive signal circuits and terminate cable shields according to the grounding design of the protection system. Separate communication wiring from high-current power conductors to reduce electromagnetic interference.\u003c\/p\u003e\n\u003cp\u003eVerify auxiliary supply voltage compatibility before energizing the device. Confirm CT and VT secondary wiring polarity, phase identification, and protection setting parameters before commissioning. Network connections should be checked for correct fiber, Ethernet, or serial communication configuration before integration into the substation automation system.\u003c\/p\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":44494864285784,"sku":"URRHH","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/UR8RH.jpg?v=1785749633","url":"https:\/\/www.industriaxplc.com\/id\/products\/ge-multilin-urrhh-ur-rhh-universal-relay","provider":"IndustriaX Limited","version":"1.0","type":"link"}
