NOTICE
Safe electrical isolation
For 24 V DC power supply, use only power supply units with safe electrical isolation
(SELV/PELV) in accordance with IEC/UL 61010-2-201 or IEC 62368-1.
The supply voltage must be within the specified voltage range.
Applies to non-isolated plant installation: 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.
The supplied power supply connector is designed for cables with a maximum cross-section of
2.5 mm².
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.
Observe the corresponding connection diagrams in the Quick Install Guide supplied with your
PRO device.
