Hey all, thanks for plugging me in.



We have no issue with doing a secondary review to ensure that we don’t have any concerns. I may get one of our staff electrical engineers to reach out and provide their thoughts.



I’m heading to another meeting now, so I’ll see how we can support once I get wrapped up.

good catch mindy,  marc, tyler, brian

we don't want to assemble that which doesn't comply with electrical safety regulations

Hi Bogdan,



Has anyone from safety looked at these? The connectors have some specifications that are lower than 2 kV.



Fisher D 107 Z051

Smiths Interconnect D01EEB306FSTAH



I'm not sure on the cable (it just has generic markings), but that would need to be checked as well.



I've CC'd Chad as he is the electrical SME.



Before Mindy can even start assembling these we would need to know they're okay to be used. There's also a question on parts availability, but that can be addressed later.



Thanks

Brian

High voltage supply for the ECAL calorimeter. Max voltage is 2000 Volts.

Hi Mark,



I would like to get some additional information about the patch panel boxes. Could you please provide the purpose of the boxes and what is the maximum voltage they will receive?



Thanks,



Mindy
