The VW3AE0825 is a plinth for top cable entry, designed for Altivar floor-standing enclosures with separate air flows or the compact version. It fits the Altivar 61 Plus, 61 Plus-LH, 71 Plus, and 71 Plus-LH drive ranges.
This is an enclosure accessory — specifically a plinth that mounts under the drive cabinet to route cables upward through the top entry. It's for the Altivar floor-standing enclosures, the ones with separate air-flow paths or the compact footprint. If you're retrofitting or replacing a cable-entry panel on an existing Altivar 61/71 Plus cabinet, this is the factory-matching part.
