Couple of things:

1) Why is the hipot test needed for a low-voltage device?

2) I *assume* that the hipot test is done the standard way: connect 
both power input terminals together, then apply the test voltage 
between those input terminals and the case / enclosure.  Output 
terminals (if any) are floating.

Is that in fact what they propose to do?


Regardless, I'd suggest finding out why they think that hipot testing 
of a low-voltage device is necessary.
