RE: Connecting a Generac ATS to an MEN supply system

It is a bit of a difficult situation because normally you would want an "international" generator and transfer switch for 230V 2 wire service but you also are 60 Hz, not 50 Hz.
Beware of unintended consequences. Do at your own risk. Contact Generac for ideas also.
It looks like if you feed 230 V into N1/N2, it would sense and switch correctly. Some modification required to the transfer switch. No current flowing in the N2/T2/E2 side.
You would also need to modify how the battery charge T1/00/T2 gets its power but it appears it can handle 240 volts at least.
Leave the 22/33 unconnected to system neutral and remove the battery charge neutral from that and hook to system neutral.
Bypass the second side of the generator main breaker to keep neutral solid to the system.
There may be something I am missing. I would want to be on site to do this.
Would you have a wiring diagram of the ATS (RXSW200A3) at your disposal to share, so that I can follow along and attempt the modifications you are suggesting?
When you say "It looks like if you feed 230V into N1/N2..." Do you really mean N1 or N2, as you later suggest that I leave one side of the breaker vacant and tied the neutral solid?
Jim, in anticipation of your reply
