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.

DANGER
Power supply units, whose net connection is designed for overvoltage category
III, can be connected to a net voltage with overvoltage category II or overvoltage
category III, see "Wiring 400 V" on page
NOTICE
Ensure that the functional earth ground is connected, because otherwise the
electronics can be destroyed by a potential difference between the VDP
08.3/40.3 and the PC if the voltage supply is interrupted to only one device and
established again. A direct connection of the functional earth ground (FE) be‐
tween VDP xx.3 display and VPB 40.3, VSB 40.3 is optimal. If the functional
earth ground is wired at a neutral point, also the control cabinet PC (VPB 40.3,
VSB 40.3) is to be connected to this neutral point.

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.
