Strip field wiring to exact length (8 mm to 10 mm) without nicking conductors. Insert wires firmly into the spring-loaded pressure clamps until seated. Maintain a minimum separation of 50 mm between low-voltage signal wiring and high-voltage power distribution lines to prevent electromagnetic interference. Verify that field cable shielding is grounded at a single point according to system engineering specifications.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":48545277739198,"sku":"ATA4D-00 S2","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-06-11_15-20-15_61ebae1c-c97a-4ab4-9de4-680fef3121d0.png?v=1785987283","url":"https:\/\/www.autooiltech.com\/products\/yokogawa-att4d-00-s2-terminal-interface-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
