Hypothetically...You would then need to have two Surge-EMS systems installed
One for the Incoming shore power, and one for the Onan generator.

Please correct me if Iím wrong.

All Surge/EMS hardwired installations (and instructions) are suggested to be after the ATS
Progressive has always stated the their permanently installed EMS be installed in the power cord before the ATS.

Cut the RV power cord about three (3) inches greater than the distance from the
junction box [ATS] to the desired location of the EMS control box. Then strip back the
outer insulation three (3) inches on input, and three (3) inches on output cable.

See visual references on page 9.
