Broken stud terminals on Mulitplus-II

Hi All

I have recently experienced broken stud terminals on the Mulitplus-II 8kVA and 10kVA 48V 230V units. When tightening the nuts with a torque wrench the AC studs break almost with no force.

I see there is a lot about this in the old forum:

Any else seeing this?
