The following table shows a possible installation configuration,
compliance with which causes the output circuit of an LOS,
LOR, or LOK4000 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.
However, it is the sole responsibility of the installer to assure
the compliance with the relevant and applicable safety
regulations.

e.g. IEC/EN 60950
Description of Options
Option F: Built-in Second Fuse
A built-in second fuse in the neutral input line enables safe
connection to the mains where phase and neutral are not
defined or cannot be identified as e.g., in the case of plug and
socket connection to the mains via Schuko-plugs, see also
Installation Instruction.
Option K: System Connectors
For installation into systems using preassembled harnesses
the converters are available with connectors fitted with screw
terminals. The system connectors are UL-listed and approved
for currents up to 10 A. Wire cross-sections: Solid wires 1.5
mm2 (AWG14), stranded wires 1 mm2 (AWG16).
