Hi All, We are going through a DFMEA process for an enclosure we have designed but are having trouble determining which components to analyze. We know we want all the safety rated components and likely the upstream components of those as well. We're unsure if we should include components related only to functionality or how granular we should get with the components upstream of the safety components. For example do we include the wire feeding the safety controller or what about the terminal blocks? Is anyone familiar with where the limit for component criticality usual falls for DFMEAs?
