Manufacturer Narrative

Philips has investigated this complaint.Several factors contributed to the shock received by the field service engineer: non-routine troubleshooting: a screw was not tightened enough to ensure a secure connection between the k1 relay to the enf1 breaker, causing field service engineer to start troubleshooting.The field service engineer did not use personal protective equipment or electrical safety gloves while working on unprotected energized circuits.The non-routine troubleshooting has to be performed by the fse due to a factory assembly failure because of which the screw was not tightened enough.Philips checked the assembly process for tightening of the screw and found no issues.Employees involved in the assembly process have received additional training to check that the screws are properly tightened.The sequence of events leading to the shock could not be reproduced.No similar complaints have been identified.Philips concludes that this is an isolated case.Philips has reviewed the velara repair manual and confirmed that it describes safety precautions to be undertaken by the field service engineer to avoid electrical shock during service work.Following this event, philips has issued an additional internal safety alert on november 8, 2019, describing this situation and the safety related precautions that field service engineers need to follow in such situations.
