          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.
