Issue:
Using a rotary phase converter with an ATS48/22

Environment:
All models, all serial numbers

Product Line:
Altistart ATS22 and ATS48

Cause:
Application notes

Resolution:
We do not recommend using a rotary phase converter with our soft starts, because the soft start will see the phase imbalances and cause problems.  Another solution would be to use a drive instead as the phase converter to feed the motor. You can select from the single phase rated drives that Schneider offers. If an offer is not available in a particular hp size then please contact local Drives Specialist who can make recommendations.
