Leakage Current
A leakage currents flows due to internal leakage capacitance
and Y-capacitors. This current is proportional to V_i and the
input frequency, when neutral and protective earth are
correctly connected as for class I equipment; see table 11.

Safety of Operator-Accessible Output Circuits
The output circuit of the converter is an SELV circuit according
to the IEC/EN 60950 -1 related safety standards.
The following table shows a possible installation configuration,
compliance with which causes the output circuit of an LOS,
LOR or LOK4000 converter to be an SELV circuit up to a
configured output voltage (sum of nominal voltages, if in series)
of 36 V.
However, it is the sole responsibility of the installer to assure
compliance with the applicable safety regulations.

Description of Options
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.
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).
G: RoHS
RoHS-compliant for all six substances.
K: System Connectors
For installation into systems using preassembled harnesses
