How to connect Rbuz D25t with RCD and automatic machines?

Mikhail Alekseevich asks:
How to properly connect in series RCDs and machines after Rbuz D25t? Without Rbuz, it is usually an RCD, then an Automaton and to the load. The instructions to Rbuz are different. The Rbuz relay is followed by an Automatic and then an RCD.
The answer to the question:
Hello! It doesn't really matter! If only the zeros did not combine before and after the RCD. Do you put it on input or to protect a specific group? Why do you want to deliver it to the machine?
