The VW3A9653 is a DNV certification kit from Schneider Electric — a set of shock-absorbing mounts and fixing accessories designed for ATV61/71 size 6 variable speed drives operating at 690 V. The kit satisfies the vibration and shock requirements of the DNV classification society, which matters if the drive is going into marine or offshore applications where class society approval is a gate item for commissioning.

What's in the kit
Kit composition is fixing accessories and shock-absorbing mounts. The mounts go between the drive chassis and the mounting plate to dampen vibration transmitted through the ship's structure or the enclosure floor. For a size 6 ATV61/71 drive — roughly 200+ kg depending on the variant — the mounts need to carry that static load while isolating the drive from hull vibration frequencies that could loosen power connections or fatigue the PCB.
