We discovered the problem when we tried to size reactors to put upstream of the chiller. After we selected the reactors, we needed to look into what the voltage drop would be on motor starting. Turned out the reactor would have knocked the voltage down too low. When they give you operating voltage tolerances, they are giving you a maximum upstream impedance. When they give you SCCR, they are giving you a minimum upstream impedance. When they give you a minimum that is greater than the maximum, it is impossible to power the unit at the rated voltage. I wrote them a letter telling them they needed to recall all the chillers that were built that way. That got their attention.How did you pull this off….I would think most would tell you that’s someone else’s problem.
