Ensure the rack power supplies are rated to accommodate the current draw of the module. To prevent electromagnetic interference, use shielded, twisted-pair cabling for all transducer inputs and route speed sensor lines away from high-voltage AC cables. The outer shield must be grounded at the monitor end only. Ensure appropriate ventilation is maintained inside the enclosure to keep operating temperatures below 65 degC.\u003c\/p\u003e\n\n\u003ch3\u003eCompliance and Certifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCE Compliant\u003c\/li\u003e\n  \u003cli\u003eCSA Class I, Division 2 \/ Zone 2 Hazardous Areas\u003c\/li\u003e\n  \u003cli\u003eATEX \/ IECEx Zone 2 Compliant\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":52668298559851,"sku":"3500\/53-03-01","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/350053-03-01-ywwuzflmcae_6eb04bd2-10c6-421f-987a-a0da02a9f29a.jpg?v=1765520486","url":"https:\/\/www.plcprotech.com\/fa\/products\/bently-nevada-3500-53-03-01-3500-series-electronic-overspeed-detection-system","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
