The VW3AE0722 is a cable-entry accessory for the top of an Altivar floor-standing enclosure with separate air flows or compact version, belonging to the Altivar 61 Plus and Altivar 71 Plus drive range.
The accessory mounts to the top of the Altivar floor-standing enclosure, routing power and control cables into the drive cabinet while maintaining the enclosure's separation of air flows. It is a cabling accessory, not a functional drive component — its failure mode is mechanical (cracked plastic, gasket degradation) rather than electrical.
