Need assistance with electric enclosure please (CSMIO/AC Contactor issue)

[Clive S]

after some research I realized that all ground contacts should be connected and not rely back panel, anyway I need confirmation of another issue please

when connecting the VFD with contactor, should all wires ( L,N,Gnd) be connected through the poles or can I just connect the Live with contactor and rest direct from mains power?

what about the DC output power supply for the drivers?

thanks!

If you really want to connect the VFD through the contactor then just the live would be fine (and not the N or E), but having said that I suppose it depends on the power system to your building as it may be different than the UK.


I personally would not connect the mains VFD through the contactor but would just connect the signal wire to make it stop.

The DC output from the power supply should not go through the contactor either .

Perhaps you should find somebody local to give you some help with this before you get a chance to damage it all or yourself.
