▪ If both low voltage and extra-low voltage are connected in the device, it
must be ensured that the circuits for extra-low voltage and for low voltage
in the connection area and in the cable are separated from each other
with double insulation.
▪ Devices with a plug connection may be connected via the device plug to
either only extra-low-voltage circuits or only low-voltage circuits.
