The VW3AE0915 is a factory-matched air conditioning unit for Altivar 71 Plus and Altivar 61 Plus floor-standing enclosures — specifically the versions with separate air flows or the compact cabinet variant. It's not a generic cooler; it's the OEM accessory designed to maintain the internal ambient within the drive's rated temperature range, which matters when the enclosure is sealed against dust or washdown.
Destined for the Altivar floor-standing enclosure with separate air flows or compact version — not the standard IP23 or through-flow cabinets. If you're retrofitting a drive that already has the separate-air-flow plenum, this unit bolts in as the thermal management module. No field wiring modifications needed; it's a mechanical and electrical drop-in for that enclosure variant.
