Hello Christine,
No violation at all. IEC/EN 60950-1/UL60950-1/CSA C22.2 60950-1 allow the plug on the power supply cord or the appliance coupler to serve as a disconnect. For your info, most swithes on ITE equipment are single pole - they are not double-pole and do not have the 3 mm contact gap to qualify them as a disconnect device to shut off the system for servicing.

( FCC class A in the US ) We noticed that the unit DOES NOT have a power switch or a mains disconnect. In order to turn the unit off you have to pull out the plug from the unit or the wall. This units runs on 120V- 220V auto-range. Does this violate any safety rules in the US or Europe? The unit has an NRTL mark on it but is seems a little bizarre that it does not have a way of disconnecting power other than pulling out the plug. Anyone have any clarification on this......
