Hi Jennifer, I would argue that the test should not be applied that port, simply because that port is fed from a 24V supply upstream. It is perfectly reasonable to specify in the product documentation that the supply upstream must meet the requirements. Why make the compliance process more onerous?
Furthermore, Annex A, and Annex B of EN61000-4-5, recognises a product such as yours by allowing you to specify the installation classification, e.g. Class 0, look at Table A.1 and all the tests are not applicable.
