High electrical voltage! Danger to life and risk
of injury caused by electric shock or bodily
harm caused by supply voltage on the
protective extra-low voltage (e.g. +24 V)!
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
fig. 5-20 "Power routing 400 V" on page 27
Danger to life and risk of injury caused by
connection of power supply units, which
cause protective extra-low voltage (e.g. +24
V), to supply voltages, for which they are not
designed.
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
fig. 5-20 "Power routing 400 V" on page 27
Material damages to electronics due to
missing functional earth!
NOTICE
Ensure that the functional earth is connected, because otherwise the
electronics can be destroyed by a potential difference between the
VDP 16.3/40.3/60.3 and the PC if the voltage supply is interrupted to only
one device and established again. A direct connection between the functional
earth and the display VDP xx.3 and VPB 40.3 and VSB 40.3 is
recommended. If the functional earth is wired at a neutral point, also connect
the control cabinet PC (VPB 40.3, VSB 40.3) to this neutral point.
