Connection
1. Connect X1S1 for the 24 V voltage supplies to the industrial power units.
Use 24 V industrial power supply units acc. to DIN EN 60742, classification VDE
0551, for example "VAP01.1H-W23-024-010-NN" (part number R911171065) for
the voltage supplies.
For specifications of the operating instructions of the power supply unit, refer to
"Related documents" on page

Danger without safe separation!
Both voltage supplies have to be galvanically
isolated
