The affected device was made available for further investigation at the manufacturer¿s site.Based on the device inspection and the assessment of provided information the reported event could be verified.The inspection of the device shows that one of three capacitors was damaged and components in the vicinity of the damaged capacitor show traces of overheating and melting.The electrolyte capacitors are components of the electrical inlet circuit of the power supply.The observed damage is typical for an electrolyte capacitor, which was exposed to overvoltage.No further information was provided regarding the reported power surge on request, however, based on the investigation results it could be concluded that the mains voltage was beyond the tolerance limit of 264 v and caused the capacitor to fail.Overheating and melting of components was caused by the overheated and damaged capacitor but stopped autonomously.In the current event, neither patient involvement nor user health consequences were reported.The device was not in use during the event but was plugged in and charging.The manufacturer comes to the conclusion that the reported problem was caused by exposing the device to conditions outside of its technical specification of the device according to its instructions for use.The number of similar cases, related to the same root cause, is within the expected range of the respective risk assessment and thus accepted.
