Maintain a minimum clearance of 100 mm above and below the unit, and 50 mm on both sides to allow adequate airflow. Verify that the ambient operating environment remains between -10 and 50 degC and is free from conductive dust, corrosive gases, and excessive moisture. Ensure a dedicated, low-impedance protective earth (PE) ground connection is established prior to energizing the main power circuits.\u003c\/p\u003e\n\n\u003ch3\u003eCompliance and Certifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCE marked for low-voltage and EMC directives\u003c\/li\u003e\n  \u003cli\u003eUL and cUL Listed\u003c\/li\u003e\n  \u003cli\u003eRoHS Compliant (6\/6 substances)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mitsubishi Electric","offers":[{"title":"Default Title","offer_id":53102131478891,"sku":"FR-A840-90K-1","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/fr-a840-90k-1-dxpscs5gvey.png?v=1776137476","url":"https:\/\/www.plcprotech.com\/fa\/products\/mitsubishi-electric-fr-a840-90k-1-fr-a800-series-variable-frequency-drive","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
