Can the ATS48 soft starter work with a roto-phase?

Customer has a Roto-phase in front of the ATS48 supplying the third phase.

Product line:  
Altistart 48

All models, all serial numbers   

Customer only has single phase available. 

It is not recommended to use a Roto-Phase to supply the ATS48 soft start because the line voltages will be imbalanced.  The ATS48 will detect a input phase fault.
