The manual most likely has a variety of different methods.
Simplest, with the built-in auto transfer switch (ATS) is:
Incoming shorepower>>>a breaker>>>I/C>>>your existing AC distribution panel.
All the others are based on what you have on your current
AC panel and how you want to wire & operate the I/C.
We have a Freedom 15.
What you wrote won't work. It will backfeed.
Learn some more about AC and draw a wiring
diagram. It will come to you.
Here's what's happening:
Think of your inverter as a second incoming source of AC, just like shorepower.
The ATS determines which power goes to the AC distribution panel.
Once you understand that, you'll "get it."
