    Leakage Currents in AC-DC operation
    Leakage currents flow due to internal leakage capacitance
    and RFI suppression Y-capacitors. The current values are
    proportional to the mains voltage and nearly proportional to
    the mains frequency and are specified at an input voltage of
    264 V (50 Hz) where phase, neutral and protective earth
    are correctly connected as required for class I equipment.
    Under test conditions the leakage current flows through a
    measuring instrument (MI) as described in fig.:
    Measuring
    instrument for earth leakage current tests, which takes into
    account impedance and sensitivity of a person touching
    unearthed accessible parts. The current value is calculated
    by dividing the measured voltage by 500
    . If inputs and/or
    outputs of K-units are connected in parallel, their individual
    leakage currents are added.

    Safety of operator accessible output circuit
    If the output circuit of an AC-DC converter is operator ac-
    cessible, it shall be an SELV circuit according to the IEC/EN
    60950 related safety standards.
    The following table shows a possible installation configura-
    tion, compliance with which causes the output circuit of an
    K series AC-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 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
    Technical Informa-
    tion: Safety.
    If the K series AC-DC converters are used as DC-DC con-
    verters, please refer to the data sheet
    DC-DC converters
    >100 W: K series.
