1 The front end output voltage should match the specified input voltage range of the DC-DC converter.
2 Based on the maximum nominal output voltage from the front end.
3 The earth connection has to be provided by the installer according to the relevant safety standard, e.g. IEC/EN 60950.
4 Earthing of the case is recommended, but not mandatory.

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.
The following table shows some possible installation con-
figurations, 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
nominal voltages if in series or +/– configuration) of 35 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:
Technical Infor-
mation: Safety.
