10.5 Electric installation
Danger of personal injury due to incorrect
mounting or electric installation!
● Any dangerous system states, which might cause personal injury, must be pre-
vented!
● Protection upon direct and indirect contact must be ensured by the specified
measures (connection to protective conductor, insulation, etc.).
10.5.1 External power supply unit
All control components are supplied from 24 V voltage supplies.
Use the Bosch Rexroth power supply unit VAP01.1H-W23-024-010-NN, part num-
ber R911171065, for the logic supply. For further information on the external
power supply unit and on the creation of overvoltage categories, refer to the
documentation of the power supply unit.
All lines of the 24 V voltage supply have to be routed separately from lines carry-
ing higher voltages.
All peripherals, such as digital sensors or actuators connected to the interfaces
of the control, also have to comply with the criteria of safety-separated circuits.
