Safety of Operator-Accessible Output Circuits
If the output circuit of a converter is operator-accessible, it
shall be an SELV circuit according to IEC/EN 60950.
The
configuration, compliance with which causes the output
circuit of a K Series AC-DC converter to be a SELV circuit
according to IEC/EN 60950 up to a configured output voltage
of 36 V (sum of nominal voltages connected in series) .
However, it is the sole responsibility of the installer to
ensure compliance with the applicable safety regulations.

Description of Options
Table 19: Survey of options
-9 Extended Temperature Range
Option -9 extends the operational ambient temperature
range from –25 to 71 °C (standard) to – 40 to 71 °C. The
power supplies provide full nominal output power with
convection cooling. Option -9 excludes inrush current
limitation by NTC.
E Inrush Current Limitation
The converters exhibit an electronic circuit replacing the
standard built-in NTC, in order to achieve an enhanced
inrush current limiting function.
