The VW3A9642 is a DNV certification kit from Schneider Electric, designed for the ATV61 and ATV71 variable speed drive series. It bundles shock-absorbing mounts, fixing accessories, and an EMC input filter into one package to satisfy the requirements of the DNV certification body for marine and offshore applications.
What's in the Kit
The kit composition includes shock-absorbing mounts to dampen vibration on the drive chassis, fixing accessories for panel mounting, and an EMC input filter to attenuate conducted emissions on the line side. The filter is sized for the drive's input current — no separate line reactor needed for basic marine EMC compliance.
Deployment Context
This kit is specific to ATV61 and ATV71 drives destined for DNV-classed vessels or offshore installations. The shock-absorbing mounts reduce transmitted vibration from the drive enclosure to the ship's structure, while the EMC filter keeps the drive within the emission limits required for marine electrical systems.
