The directive says "designed or adapted for use with......"  the
voltages ranges you state.

If you product is not intended for use with such voltages then I do not
see you need to seek approval (LVD) irrespective of what you rate the
isolation.

Having said that if you state a rated isolation then you need to be sure
you meet it.

How is your unit powered? Sounds like an external wall brick adaptor -
this will of course need to comply.
