Yeah my intuition on it is that its causing some sort of ringback noise from the motor. A pal of mine has suggested an inductor on the output as a filter but before I start throwing extra parts on the system I would like to know why its doing this. We can and will run it in Wye but there is HP loss when you do that and the german in me tells me that its not proper to run a device differently than its designed for. Seeing as we have several of these out in the field I would rather be prepared for the next time this comes up
