Well, after reading and reading these block diagrams, I can not figure out where DC link is in my cabinet..

the paper reads....

L to master switch

Something that is X501 ( I cannot find a X501 anywhere )
Then to K1 ( relay, I cannot determine what is or where )

Then to N

K1 on the other page is at the big relay with L1 L2 L3... and then PE

Now, L1 is 120v AC , L2 is 120v AC , L3 is 220v AC

then this goes to K2...

Then it shows that K2 has something to do with Board G0 at X121... now I know where this is, and pins 9 and 63...

So, it looks like K2 relay closes, and provides power to U V W ... it appears that this is 165v AC at U V W ....

What is the point of DC Link you want me to find?
