PE bars are to be installed preferably on the mounting plate.
In case of isolated PE bars, both ends must be connected to the mounting plate
by means of copper strips with a maximum length of 20 cm.
The cross-section of the copper strips has to be at least equal to that of the incoming mains cable.

High electrical voltage! Danger to life and risk
of injury caused by electric shock or bodily
harm caused by net voltage on the protective
extra-low voltage (e.g. +24V)! Connection of
power supply units, which cause protective ex‐
tra-low voltage, to net voltages, for which they
are not designed.
DANGER
Power supply units, whose net connection is designed for overvoltage category
II, are to be connected to a net voltage with overvoltage category II, see
