Hi John While I am not familiar with the Trumpf brand, (interesting resemblance to TRUMP), and I am not aware if the connection between the EPJ and the top of the pendent is compliment, I do agree with your interpretation for a second connection to the metal surrounds. Does the pendant itself have TGA approval as a medical device?
We had similar issues with the earthing of Stryker pendant, signal outlet metal surrounds, but were advised that as they had TGA approval as a medical device it was outside the scope of 3003:2011. (The LV outlets did however comply in that pendent, and I believe they were still within the scope of 3003) I would be checking out the compliance of connections at the top of the pendent and earthing conductors/connections within the pendent?
