Strip the outer cable jacket at the module terminal block entry point and expose the bare metal shield braid. Clamp this braid securely to the functional ground (FE) rail using a dedicated B\u0026amp;R X20 shield termination clip assembly. Connect the internal signal ground wire to the designated COM reference terminal on the module to equalize ground potentials between different bus nodes.\u003c\/p\u003e\n\u003ch4\u003eMechanical Slot Insertion and Hot-Swapping\u003c\/h4\u003e\n\u003cp\u003eTo integrate the X20CS1030, press the electronics module firmly into a pre-installed X20 bus base module until the upper and lower integrated plastic locking tabs engage with an audible click. Ensure the interface block sits perfectly flush against the surrounding X20 slices. While the X20 system architecture supports hot-swapping under specific software configurations, it is recommended to isolate the field interface power before inserting or extracting the module to prevent transient communication glitches on the active X2X backplane link.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"B\u0026R","offers":[{"title":"Default Title","offer_id":53086373445995,"sku":"X20CS1030","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/X20CS1030-dcb5lb2e1yo.png?v=1776138172","url":"https:\/\/www.plcprotech.com\/fr\/products\/b-r-x20cs1030-x20-system-rs485-rs422-communication-module","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
