DC 24 V Voltage Supply

The USB connection is performed in the limited full speed mode. Only key‐
boards and mice can be connected to the VDP. No internal HUBs are to be
integrated into these USB devices. Other USB devices, such as memory sticks,
are not supported. The S1 switch 2 must be in the "ON" position.
For information about the cable lengths related to the display resolution, see
chapter 10.4.4 "Cable connections and cable types allowed" on page

A standard 24 V industrial power supply unit can be used for the voltage supply.
NOTICE
In this case an isolated power supply unit is to be used.
There are two possibilities to connect the external VDP 08.3/40.3 operator dis‐
play to the 24 V voltage supply:
● Connection to the 24 V Out of the external UPS (if available).
For this variant, the display and the control cabinet PC are switched off at
the same time by the UPS. The user can carry out actions manually when
there is a power failure of 24 V or if the control cabinet PC is switched off
while the PC is shut down.
● Direct connection to the 24 V supply voltage.
If there is no supply voltage of 24 V, the operator display immediately
darkens. The user cannot execute any actions via the operator display
during the shutdown of the control cabinet PC.

If the distance between VDP and control cabi‐
net PC exceeds 50 m, equalizing currents may
flow when using a non-isolated power supply
unit because pin 2 is internally connected to
the housing.
