The VW3AE0807 is a plinth for cable entry via the top, designed for Altivar floor-standing enclosures in the Altivar 71 Plus, Altivar 61 Plus-LH, and Altivar 71 Plus-LH ranges. This accessory routes incoming power and control cables into the drive cabinet through the base, keeping the top surface clear for ventilation or bus work.
The plinth bolts to the bottom of the floor-standing enclosure before the drive is installed. Cable entry via the top means the incoming cables drop down through the plinth into the cabinet's wiring channel, which keeps the gland plate accessible without removing the drive. This matters for a retrofit or a line-down swap: you need the enclosure footprint and the bolt pattern to match, and the plinth height must clear any floor-mounted cable tray.
