If the output circuit of a AC-DC converter is operator-accessible,
it shall be a SELV circuit according to the related IEC/EN 60950
safety standards.
The following table shows a possible installation configuration,
compliance with which causes the output circuit of an LS Series
AC-DC converter to be a SELV circuit according to IEC/EN
60950 up to a configured output voltage (sum of nominal voltages
if in series or +/– configuration) of 36 V.
If the LS converters are used as DC-DC converters, please refer to
the previous section.
