    Input Fuse
    A fuse holder containing a slow-blow type fuse (Dimension:
    5
    × 20 mm) is mounted in the converter's back plate. The
    fuse protects the module against severe defects. It may not
    fully protect the module at input voltages exceeding
    200 V DC. In applications where the converters operate at
    DC source voltages above 200 V DC, an external fuse or a
    circuit breaker at system level should be installed.
    For applications where the fuse should be inaccessible: see
    Option F.
    Input Under-/Overvoltage Lock-out
    If the input voltage remains below 0.8
    Ui min or exceeds
    1.1
    Ui max (approx. values), an internally generated inhibit
    signal disables the output(s). When checking this function
    the absolute maximum input voltage rating
    Ui abs must be
    carefully considered (see table:
    Input data). Between Ui min
    and the undervoltage lock-out level the output voltage may
    be below the value defined in table:
    Output data (see: Tech-
    nical Information: Measuring and Testing).

    Reverse Polarity
    Reverse polarity at the input of AM, BM, CM, DM, FM and
    CMZ, DMZ types will cause the fuse to blow. In EM, LM and
    LMZ types a series diode will protect the module. A series
    diode is not incorporated in AM, BM, CM, DM, FM and
    CMZ, DMZ types to avoid unwanted power loss.
    Inrush Current
    The CM, DM, EM, LM and CMZ, DMZ, LMZ (excluding FM)
    modules incorporate an NTC resistor in the input circuitry
    which (during the initial switch-on cycle) limits the peak in-
    rush current to avoid damage to connectors and switching
    devices. Subsequent switch-on cycles within a short inter-
    val will cause an increase of the peak inrush current due to
    the warming up of the NTC resistor. Refer also to:
    Option E
