What the kit contains and what it does
The kit composition includes shock-absorbing mounts and fixing accessories. These mount between the drive chassis and the panel backplate to dampen transmitted vibration, protecting the drive's internal components and maintaining the DNV type-approval for the assembly. Rated for use with ATV61 and ATV71 drives at 690 V in size 8 enclosures, this is a mechanical accessory — no electrical connections or wiring changes are involved.
