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 standards, e.g. IEC/EN 60950.
4
Earthing of the case is recommended, but not mandatory.
Safety of Operator-Accessible Output Circuits
If the output circuit of a DC-DC converter is operator-accessible,
it shall be a SELV circuit according to safety standard
IEC/EN 60950.
The following table shows some possible installation
configurations, compliance with which causes the output circuit
of a DC-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.
