Removing the control from the top-hat rail
1.
Remove the left end clamp.
2.
Use a suitable tool (e.g. slotted screwdriver) and put it into the lower disengaging mechanism
(base latch) of the control and disengage the control (see (A) in the following figure). The base
latch is locked in the open position.
3.
Remove the control vertically to the mounting rail [see (B)] in the following figure).

10.5 Electric installation
10.5.1 External power supply unit
WARNING
Danger of lethal injury due to hazardous electric voltage
−
Connect power supply units generating protective extra-low voltage (24
V) only to supply voltages designed for these power supply units. Note
the overvoltage categories (refer to the documentation of the power
supply unit).
−
Do not apply the supply voltage to the protective extra-low voltage.
All control components are supplied from 24
V voltage supplies (SELV/PELV).
Use the Bosch Rexroth power supply unit VAP01.1H-W23-024-010-NN, part number 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 carrying 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.
The 24 V voltage supply can be grounded. For more detailed information, refer to the docu-
mentation of the power supply unit.
