The VW3AE1901 is an additional electrical input isolation accessory for Schneider Altivar floor-standing enclosures with separate air flows or compact versions, specifically the Altivar 61 Plus, Altivar 71 Plus, Altivar 61 Plus-LH, and Altivar 71 Plus-LH drive families. It requires a 24 V DC buffer voltage for its condition of use, meaning the isolation circuit is powered separately from the drive's main DC bus — a detail to confirm when wiring into an existing cabinet.
