For all input sources, other than DC MAINS, where the input
voltage is between 60 and 75 Vdc (Classified as TNV-2 in
Europe), the following must be adhered to, if the converter’s
output is to be evaluated for SELV:

The power module has ELV (extra-low voltage) outputs when
all inputs are ELV.
All flammable materials used in the manufacturing of these
modules are rated 94V-0, and UL60950A.2 for reduced thick-
nesses. The input to these units is to be provided with a max-
imum 10A normal-blow fuse in the ungrounded lead.

remain withing SELV limits even with internally-generated
non-SELV voltages. Single component failure and fault
tests were performed in the power converters.
One pole of the input and one pole of the output are to be
grounded, or both circuits are to be kept floating, to main-
tain the output voltage to ground voltage within ELV or
SELV limits.
The input source is to be provided with reinforced insula-
tion from any hazardous voltage, including the AC mains.
One VI pin and one VO pin are to be reliably earthed, or
both the input and output pins are to be kept floating.
Another SELV reliability test is conducted on the whole
system, as required by the safety agencies, on the combi-
nation of supply source and the subject module to verify
that under a single fault, hazardous voltages do not appear
at the module’s output.
