Danger of destroying output
"+5V repeater supply" by overload!
NOTICE
Do not short-circuit the output.
Do not exceed the maximum current.
Bus connectors
The PROFIBUS connectors each have a connectable terminating resistor.
The terminating resistor must always be active at both the first and last bus
node. Carry out the connection as shown in the figures below.

Preparing a cable for connecting a bus connector
To assemble the bus cable, proceed as follows:
●
Use cable according to DIN EN50170 / 2 edition 1996
●
Strip cable (see figure above)
●
