10.3 Electric connection

10.3.1 Connecting 24 V supply to the control cabinet PC

1. Connect the functional earth.
2. Connect the "X10" interface for the 24 V voltage supply to the industrial
power supply unit or to the UPS (if available).
For details on how to connect to a UPS, refer to
ing a UPS" on page
NOTICE
Ensure that the functional earth is connected, as otherwise the electronics can
be destroyed by a potential difference between the operator display and the
control cabinet PC if the voltage supply is interrupted to only one device and es-
tablished again. A direct connection of the functional earth between operator
display and control cabinet PC is optimal. If the functional earth is connected to
a neutral point, the control cabinet PC and the operator display have to be con-
nected to this neutral point.
For the voltage supply, 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).
