    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.
