Hello guys,
Thank you to all those persons who helped me pass my project in Engineering.
Now I am in trainibg of Service engineer at industry.
Our electrical supervisor who does all the wiring and he doesn't want to tell about anything.
We are using seimens pm240 drives along with 3-pole magnetic contactors and some seimens RCDs
So anyone can tell me what comes furst in circuit and what comes last.

 

These days a magnetic contactor is normally not used as the PM240 driver has emergency stop built inside.
But if used will be before the drive.
See diagram attached.
