2.1 Cabling
The Profibus-DP device is supplied with 10 to 30 V DC by means of the screw terminal strip on the PCB.
A screened power cable should be used. A cable according to the Profibus specifications should be used
as data cable.

2.
Set the address by means of DIP switches.
3.
Fix cover according to the installation instructions.
2.3 Terminating resistor
If the Profibus-DP device to be installed is used as last participant in the system, the terminating resistor
on the PCB must be activated. For the position of the switches see the respective installation instructions.
2.4 GSE file
A diskette with the respective GSE files (device identification records) is supplied with the Profibus-DP
manual.
