Resolution:
Q Suffix on the ATS22 was designed for the European market. Our Suggestion would be to use the S6U or S6 suffix version for the US market.
Q Suffix version does not have ground fault protection and its only for available with 460VAC input, 230VAC control voltage and 24vdc logic input control voltage.
Q Suffix Version if you are not going to use inside the Delta wiring you will need to change parameter setting dLtA to LINE. If you are using inside the delta wiring leave dLtA to dLT.
