The VW3AE0721 is a cable-entry accessory designed for the top of Altivar floor-standing enclosures in the Altivar 71 Plus and Altivar 61 Plus drive ranges. It routes incoming power and control cables into the cabinet while maintaining separation between air flows — relevant for the compact and separate-air-flow versions of those enclosures.
This accessory is specific to the Altivar floor-standing enclosure with separate air flows or the compact version. It provides a cable entry via the top of the cabinet, which is the typical routing for incoming line and motor cables on larger drives. If you are retrofitting into an existing Altivar 71 Plus or 61 Plus cabinet, this part maintains the original gland-plate layout and airflow separation design.
