Mount the open-style enclosure securely onto the DIN rail or panel base, ensuring proper clearance for thermal dissipation within the specified operating temperature range. Terminate field power connections to the screw terminals using solid or stranded copper wire rated at 75 deg C or greater with a maximum torque of 0.8 Nm (7 lb-in.), and verify that all communication shields are grounded properly to the cabinet earth bar to mitigate electromagnetic interference.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":45291607064691,"sku":"1794-ACN15K","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-07-30_11-27-21_52df552b-08e5-499b-bfac-221e2d2630c0.png?v=1785382848","url":"https:\/\/www.dcssupplier.com\/products\/allen-bradley-1794-acn15k-flex-i-o-controlnet-adapter-module","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
