Power down the corresponding I\/O slot before removal.\u003c\/p\u003e\n\u003cp\u003eQ: How does the cable shielding handle grounding within the DCS cabinet?\u003c\/p\u003e\n\u003cp\u003eA: The internal metal braid and foil shield terminate directly to the metal shroud of the 24-pin SCSI connector. This establishes an electrical path to the chassis ground through the module housing, provided the mating receptacle is correctly grounded to the master cabinet busbar.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBend Radius Constraints:\u003c\/strong\u003e Maintain a minimum dynamic bend radius of 10 times the outer cable diameter during installation routing. Avoid sharp right-angle bends immediately adjacent to the 24-pin SCSI connector shells to prevent conductor stress and shield separation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Engagement and Fastening:\u003c\/strong\u003e Fully insert the 24-pin SCSI connectors into the mating module or FTA receptacles. Secure all integrated retention screws or latches completely to ensure stable electrical contact under low-frequency industrial vibration regimes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Routing Separation:\u003c\/strong\u003e Route this signal cable in dedicated low-voltage wire ways. Maintain a minimum physical separation of 300 mm from high-voltage AC power distribution lines or variable frequency drive (VFD) output cables to minimize electromagnetic cross-talk.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":45246362353779,"sku":"51305478-100","price":410.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-07-16_15-34-00.png?v=1784193344","url":"https:\/\/www.dcssupplier.com\/products\/honeywell-51305478-100-scsi-cable-assembly","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
