    Option -9: Extended Temperature Range
    Option -9 extends the operational ambient temperature range
    from –25 to 71 °C to –40 to 71 °C. The power supplies provide
    full nominal output power with convection cooling. Option -9
    excludes inrush current limitation by NTC.
    Option E: Inrush Current Limiter
    CS/DS/ES/FS/LS types may be supplemented by an electronic
    circuit (option E, replacing the standard built-in NTC) to achieve
    an enhanced inrush current limiting function.
    Option E is
    mandatory for -9 models.
    CS models fitted with option E and option D6 (input voltage
    monitoring) meet the standard ETS 300132-2 for 48 VDC supply
    voltage. Option D6 (externally adjustable via potentiometer from
    36.0 to 40.5 V) is necessary to disable the converter at low input
    voltages, avoiding an excessive input current. Option D6
    threshold level should be adjusted to 44.0 - 50.0 V for 60 V
    nominal supply systems (refer to the description of option D). The
    D output can be connected directly to the inhibit input.
    Note: Subsequent switch-on cycles at startup are limited to max.
    10 cycles during the first 20 seconds (cold model) and then to
    max. 1 cycle every 8 seconds.
