The VW3A9629 is a DNV certification kit from Schneider Electric, designed for variable speed drives of the ATV61 and ATV71 series in size 9. It includes shock-absorbing mounts and the mechanical fittings — profiles and brackets — required for fixing the drive to satisfy DNV classification society requirements for marine and offshore installations.
What the kit does
The kit provides the mechanical interface — shock-absorbing mounts plus the profiles and brackets — to fix an ATV61 or ATV71 size 9 drive into a panel or enclosure in a way that meets DNV certification. The shock-absorbing mounts reduce vibration transmission to the drive chassis, which matters for marine environments where the vessel's own vibration and shock profiles are more severe than a stationary plant floor.
