Beginner needs help with wiring

So I’ve installed a 24v parking split unit ac in my semi. I have 2 12v 300ah lithium batteries that I’ve connected to make 24v. I have a Victron 500 smart battery shunt, Victron Orion 1400 XS dc to dc. I need help with the wiring diagram.
I have power coming from the starter batteries to the dc charger.
But I’m confused as to what goes where? AC wired to lithium? Where does the shunt fit in and what goes to it?

You will not get a wiring diagrams supplied. Either employ an installer familiar with Victron or start reading the manuals for each product (found under fownloads on each product page), which includes wiring diagrams examples and also read Victron wiring unlimited. Also Victron publish example system schematics. The terms of use of the community is that it is not a design service.
