[RE-wrenches] XWPro produces noise at low (<50 W Power)

[Eric Smiley]

Thanks. That was the feedback we already received. I think it is SOP for
Schneider to tell you to reinstall firmware and reset to factory - no
matter what the problem.
Fortunately, we have to go back to do some more wor - they are finally
receiving their generator. That will give us a chance to recommission the
system.
