Extract from DIN VDE 0100-410-HD 384. 1997:
The conductors every circuit SELV (Safety Extra Low Voltage) and
PELV (Protective Extra Low Voltage) system and the conductors every
other circuit must safely separated one thefollowing techniques:
- Separation the conductors;
- The conductors SELV and PELV circuits must have second
insulation layer addition their primary insulation layer;
- Conductors circuits different voltages must separated with a
earthed metal screen screening;
COMMENT: the above cases, the basic insulation conductor
only needs ratedfor the voltage the circuit belongs to. standard was created result.41 /Jan.

- The values before the slash relate the power
(contacts for high currents and voltages)
- The values after the slash relate signals
(contacts for low currents and voltages)

.2 Identification and type designation
Many the combination connectors available the market today were
developed HARTING.2.2. Other connector manufacturers have adopted
these designs introduced HARTING.
- Multicore cables, lines conductor bundles can carry the voltages of
different circuits, provided the conductors SELV and PELV circuit
are individually jointly equipped with insulation rated for the highest
voltage.
