I would only add that those details need to be consider during design, not after the design. Ralph From: Douglas Nix <0bb8ff993b10-dmarc-requ...@listserv.ieee.org> Sent: Wednesday, August 30, 2023 6:31 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] DFMEA Component

[PSES] Absence of Voltage Tester Design Flaw Impact

2023-08-30 Thread Ronan Shanley
Hi All, Thank you again for your responses about my DFMEA question they were very helpful. I have another question about safety design. We are using an absence of voltage tester (AVT) that provides a UL approved method to open an enclosure without having to put on PPE and perform a live dead

I would argue that if you impose any requirements (such as AWG size or design of terminal block) then yes absolutely you need to have those components in the test environment.It is my impression that if your system fails for any reason that could be attributed to poor installation, then the

[PSES] Looking for someone with EMC & Functional safety experience for IEC Standards development

I agree with John. FMEAs are most helpful for determining Diagnostic Coverage or β-factor when doing the functional safety analysis. Risk assessments, when done correctly, are intended to help make decisions about risk control measures, including assessing the effectiveness of existing
