Connect the "X1S1" interface for the 24 V voltage supply to the industrial power supply unit.
For the voltage supply, use a 24 V industrial power supply unit acc. to DIN EN 60742, classifica-
tion VDE 551, for example "VAP01.1H-W23-024-010-NN" (part number R911171065).

The display immediately darkens in case of a power failure if the operator display is directly
connected to the 24 V supply voltage without UPS. The user cannot execute any actions via the
operator display during the shutdown of the control cabinet PC.
If the operator display is connected together with the control cabinet PC to the "24 V Out" of
the external UPS (VAU 02.1), the user can still access the operator display during shutdown
due to a power failure.
