Cut or verify the panel cutout dimensions according to standard Mark IV mounting specifications and insert the DS3820LT4A1C1A unit securely. Fasten all mounting brackets to lock the frame against industrial vibration. Strip field leads to the correct length and secure them to the 19 side-mounted terminals using calibrated screwdriver torque to prevent loose connections. Ground all cable shields at a single chassis ground point to prevent stray electrical noise from interfering with protection logic.\u003c\/p\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":45320329658483,"sku":"DS3820LT4A","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-08-06_16-17-52_1200x1200_004595b5-5078-4484-bd60-cf38f2932fa7.jpg?v=1786005720","url":"https:\/\/www.dcssupplier.com\/ar\/products\/ge-ds3820lt4a-protective-module","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
