...You could consider calibrating your PID values. There are instructions on forum if you use google to look for the details. Or just never start out at 260C (go to 250C first, then once it settles jump up to 260C).
Thanks alot gr5! I see the problem there, the nozzle is just heating up to quick with the new 35W heater. For myself, I'll go with preheating, as you said, so it doesn't "overjump" these 275C.
But I'm afraid that people new to 3d printing just get this error everytime they try to print with the ABS profile. They'll follow the error message, go to the support faqs, check the cable connections as told and are lost, and may returning their UM2+ just because of this silly firmware-bug.
That should have turned up first in Lab when Ultimaker ran through their tests... I'll contact the support on this matter, this should be a easy one for them to correct in a new firmware.
Thanks again for your quick reply! That's the main reason i chose ultimaker, a solid community is essential

Yes. 275C. There is a setting in the marlin (marlin is the firmware in the UM2) called "HEATER_0_MAXTEMP" in Configuration.h. For UM2 printers it is usually 275C. The max temp you can set with the control knob on the printer is always 15C lower than MAXTEMP.
If you go over MAXTEMP you get an error and nothing works until you power cycle.
The UM2+ is a very new machine and evidently Ultimaker didn't adjust the PID settings (or the temp range where PID is enabled) in the firmware. This is unfortunate. The UM2+ has a 35W heater but the older machines have 20-25W heaters (nominally 25W).
Hopefully someone will make improvements to either the PID values or maybe also the temp range where PID is enabled (I think it's within 20C of target temp?). A good "D" value should have prevented this I would think. Or maybe this will require custom code just for the 35W heaters.
