The electric strength test is performed as a factory test in
accordance with IEC/EN 60950 and UL 1950 and should
not be repeated in the field. Power-One will not honour any

Safety of Operator Accessible Output Circuit
If the output circuit of a DC-DC converter is operator acces-
sible, it shall be an SELV circuit according to the IEC/EN
60950 related safety standards.
Since the M series DC-DC converters provide double or re-
inforced insulation between input and output, based on a
rated primary input voltage of 250 V AC and 400 V DC (for
class II units 250 V AC and DC), only operational insulation
is needed between the AC mains and the input of the DC-
DC converter. This means that there is no need for an elec-
trical isolation between the AC mains circuit and the DC-DC
converter input circuit to cause the output of an M series
DC-DC converter to be an SELV circuit. Only voltage
adaption and rectification to the specified input voltage
range of the DC-DC converter is needed.
The following table shows a possible installation configura-
tion, compliance with which causes the output circuit of the
DC-DC converter to be an SELV circuit according to IEC/
EN 60950 up to a configured output voltage (sum of nomi-
nal voltages if in series or +/– configuration) of 36 V.
However, it is the sole responsibility of the installer to as-
sure the compliance with the relevant and applicable safety
regulations. More information is given in:

mation: Safety.
