Push firmly until the retention latches engage completely to guarantee mechanical locking and low-impedance electrical contact. Ensure a well-ventilated installation environment to prevent thermal degradation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Shielding and Grounding\u003c\/strong\u003e: Use twisted-shielded pair cabling for all RS-485 runs. Connect the cable shield directly to the functional earth (FE) terminal at one end only to prevent ground loop currents from causing communication bit errors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring Distance and Separation\u003c\/strong\u003e: Maintain a minimum clearance of 200 mm between signal cables connected to the CI532V02 and high-voltage power distribution wiring or variable frequency drive outputs to avoid electromagnetic interference. Separate signal wires from power wires strictly according to wiring diagrams.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":45338790363251,"sku":"CI532V02","price":233.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-05-20_11-50-49_6091a85c-21a8-49f7-940a-53b5977bcc70.png?v=1786353041","url":"https:\/\/www.dcssupplier.com\/ar\/products\/abb-ci532v02-serial-communication-modules","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
