I haven’t heard that we’re supposed to be going back and adding this to all IMC-AC controllers but I have done a few of these wiring change kits on IMC-AC, VFMC, & a Motion 4000 controller. They’re sending the kit when we replace an F5 drive. For a few years now the new F5 drives have been coming with a set of Amp Traps and just this year these kits are in the box. I’ve assumed it’s because of the high failure rate of the F5 drives and we wouldn’t get warranty support if it isn’t done. I’ll check out that bulletin though.
