You are confusing two different voltage specifications here.
1. The Voltage Supply - 48VDC
2. The voltage rating of the apparatus
Where the apparatus has a voltage supply rating <50Vac or 75Vdc
then the General Product Safety Directive should be applied. This
will require the application of Due Diligence in showing safety.
Otherwise the LVD should be applied and the relevant Harmonised
Safety Standard employed.

The Low Voltage Directive (73/23/EEC) applies to
equipment that operates from supply voltages of
50-1000Vac or 75-1500Vdc.
Does this mean that strictly according to the
standard *in and of itself*, that is according
to 73/23/EEC by itself, safety testing need NOT
be applied to ANY piece of equipment that operates
from 48vdc in a Central Office?
Specifically, say a piece of equipment in the rack
that does not touch the E1 line?
What am I missing here ...
