Mike, I have had instances on the manufacturing line were the unit would fail the Hipot or Ground Bond test. The same holds true. The power supply is an approved part and was tested by the power supply house. With this information alone I would recommend doing the tests on the end product.

I've been asked why a routine hipot test is required on an end assembly computer when it uses a Listed power supply that has already been hipot tested. So far I don't like the way I've worded my response. Basically what I've said is that a power supply is approved as a component. The end safety of the device depends on the installation. Can anyone add some more beef to this statement. Thanks.
