Connection
1. Connect the "X1S1" interface for the 24 V voltage supply to the industrial
power supply unit.
Use a 24 V industrial power supply unit acc. to DIN EN 60742, classification VDE
0551, for example "VAP01.1H-W23-024-010-NN" (part number R911171065) for
the voltage supply.
NOTICE
In this case, use an isolated power supply unit.
UPS
The display immediately darkens in case of a power failure if the op-
erator display is directly connected to the 24 V supply voltage with-
out UPS. The user cannot execute any actions via the operator dis-
play during the shutdown of the control cabinet PC.
If the operator display is connected together with the control cabi-
net PC to the "24 V Out" of the external UPS (VAU 01.1), the user
can still access the operator display during shutdown due to a pow-
er failure.
