Connecting the power supply
For connecting to the standard device, observe all instructions and procedures in the underlying operating instructions.
NOTICE
Safe electrical separation
For the 24 V DC power supply of IFP devices, use only 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.
Ferrites in IFP devices
The two power supply cables from the device and Transceiver Unit require one ferrite each. Each power supply cable must be
routed twice through the ferrite. The distance between the ferrite and the power supply connector must not exceed 200 mm.
In extended operation, two ferrites are connected to the ends of the Cat. 6A Ethernet cable required. Mount the two supplied
ferrites according to the following figure on the Cat. 6A Ethernet cable:
Mount the ferrites as close as possible to the connectors and in a position that allows the Cat. 6A Ethernet cable to be secured
to the device, see section "Securing the cables (Page 20)".
Power supply connector
Note
The 24 V DC power supply must be adapted to the input data of the device, see "Technical specifications". 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 underlying operating
instructions in the section "Accessories." The power supply line must be provided with a fuse whose dimensions match the
cable cross-section used.
When connecting the power supply, note the polarity of the cables:
Power supply 24 V DC 2-pin
Pin Meaning
1 +24 V DC
2 Ground
Securing the cables
Use cable ties to secure the connected cables to the strain relief plate: Make sure that the cables are not crushed by the cable tie.
The following figure shows an example of securing the cables to the strain relief plate. Possible mounting points are marked.
