KUKA earth system

    Dear Friends

    I have question about KUKA grounding system:
    Normally we 2 earth system:
    Electrical Earth and Clean Earth (that is used for instrument component that is safe grounding and has another well earth).
    Normally that is separated with electrical well earth!!!!
    Other question: in Kuka procedures these 2 well earth should be connected to each other or not?
    For this case what is right cable cross section (cable size) for these 2 grounding system. (PE1,PE2)
    In this photo which is clean earth (attached file)?
    In my idea PE1 is clean earth ,is this right ?

    Thanks

    PE2 is 16mm^2
    PE1 is smaller and it is part of your power drop (supply). For details consult nameplate of the robot and electrical standard of your country.
    Did you see how PE1 and PE2 are installed? And how far from each other? Do you think they are isolated?

    1) read pinned topic: READ FIRST...

    2) if you have an issue with robot, post question in the correct forum section... do NOT contact me directly

    3) read 1 and 2
