Abb m2000 s4c+ power supply

You have not provided enough info for anyone to help you. I suggest that you look through the user manual portion of the forum for the schematics that match your robot and controller. Then you maybe able to find out what those wires are for and where they go.

It appears the 3 digit wire number on the wires are 131, 132, 133.

Both circuit breakers are missing. See picture.

Look at page 202 (pdf page 69) of the M2000 Product Manual - References manual found >here< for connection information.

So, ok, you provided enough for Skooter to help. I should have said no normal human!
