all debuggers I have used in the past have had the ability to decide whether the debugger will power the DUT or not. I have hunted through ulink and not found it.
if no such function exist, is it OK to cut the Vcc wire from ulink to device??

uLink-ME does not seem to have this facility;
uLink-2 does - see: http://www.keil.com/support/man/docs/ulink2/ulink2_hw_jumpers.htm (the user guide is written as the mirror image of your question!)
uLink is the same (in this respect) as uLink-2
It would be so much easier if Keil provided a diagram to illustrate this...
