Connecting or disconnecting this cable under power can damage internal logic components or cause CPU fault trip states.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum allowable continuous voltage across the internal conductors of the 1745-C2?\u003c\/p\u003e\n\u003cp\u003eA: The conductors are rated for a maximum line-to-line operational voltage of 70 V max.\u003c\/p\u003e\n\u003cp\u003eQ: Can multiple 1745-C2 cables be daisy-chained together to extend connection distance?\u003c\/p\u003e\n\u003cp\u003eA: No. Daisy-chaining cables increases backplane signal capacitance and trace impedance beyond design limits, leading to potential signal corruption or communication timing faults.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eRemove primary AC power from both the main SLC 100 processor unit and all downstream expansion units before inserting or removing the cable.\u003c\/li\u003e\n\u003cli\u003eAlign the 10-pin keyed connectors on the cable header with the mating 10-pin chassis sockets to prevent pin bending or misaligned contact insertion.\u003c\/li\u003e\n\u003cli\u003eEnsure the cable flex path maintains a minimum bend radius of 1.0 in (25.4 mm) to avoid strain on the conductor terminations.\u003c\/li\u003e\n\u003cli\u003eRoute the cable away from high-voltage AC lines, variable frequency drive motor leads, and heavy inductive loads to prevent noise coupling into backplane logic signals.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":45338789806195,"sku":"1745-C2","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/1745-C2_612cdc8a-ad78-40c0-b128-e89a1d0f0ecb.png?v=1786343914","url":"https:\/\/www.dcssupplier.com\/ar\/products\/allen-bradley-1745-c2-interconnect-cable","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
