Connecting the power supply

Note before connecting the device
NOTICE
Safe electrical isolation
Use only 24 V DC power supply units with safe electrical isolation in accordance with
IEC 61010-2-201 or IEC 60950-1 in accordance with the SELV/PELV standard.
The supply voltage must be within the specified voltage range.
Applies to non-isolated system configurations: Connect the terminal for GND 24 V from the
24 V power supply output to equipotential bonding for uniform reference potential. You
should always select a central point of termination.
Note
The 24 V DC power supply unit must be adapted to the input data of the device, see section
"Technical specifications of the IFPs (Page 109)" and
"Technical specifications of the Transceiver Unit (Page 111)".
The supplied power supply connector is designed for cables with a maximum cross-section
of 2.5 mm².
Additional information on the supplied power supply connectors and additional permitted
power supply connectors can be found in the section "Accessories (Page 25)".
The power supply line must be provided with a fuse whose dimensions match the cable
cross-section used.
Procedure
The following figure shows the connection of the power supply using the example of the
IFP1500 V2 built-in device and applies in the same way to all other IFPs and the
Transceiver Unit.
Note
Cable routing for PRO devices
As the PRO device is not installed in a control cabinet but on a pedestal or support arm, the
connecting cables must be routed through the support arm or the pedestal. The cable cross-
sections specified for the built-in devices also apply to the PRO devices.
Make sure to consult the corresponding connection diagrams in the Quick Install Guide
supplied with your PRO device.
