Missing CRM99 on R-30iA

I have an R-30iA cabinet that seems to not have the CRM99 on the panel board. Is this normal? It isn't a big deal for our application but it is puzzling, as I don't see anything in the manuals indicating that it is part of an option.

Ok, I figured it out. The maintenance manual and the DCS manual show different schematics. I'm assuming at some point it was changed, but my controller uses the CRMA8 on the board.
