PE bars should be preferably installed on the mounting plate
in a conductive manner. In the case of isolated PE bars both
ends must be connected to mounting plate by means of copper
strips with a maximum length of 20 cm.
(3) 0.75 mm up to 6 m
1.5 mm up to 10 m
Distances exceeding 10 m require
a separate local power supply

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
The power supply unit with safety transformer according to EN 60742 must
comply with overvoltage category III, see fig. 7-23 "Wiring of the DC 24 V power
connection to the VPB 40.1" on page 42 .
X20 – AC 230/115 V Power Supply
This connection is used for device variants for AC 230/115 V.
All internally required voltages are generated by the AC 230/115 V power sup‐
ply unit.
