Good day!
We have KUKA KR2150 and (V)KRC2, and now we're try to start it up.
"Operating Instructions" says, that robot body must be connected with separate wire 16mm2 to KRC2.
And on KRC pannel, I can see a beautiful screw connection for it (#12 on image).
But I can't see anything suitable on robot's connection panel (#4 is located in nowhere).
So, should I connect it just to foot bolts?
P.S. And btw, is that connection is neccessary for first run of robot? Or i can use only data and power cable (X20 X30) for it?
(Because, as I understand, X20 includes two grounding pins)
Is it for human safety or I'll burn down robot controls if will not connect it?
