Connecting the Bus Connector
Proceed as follows to connect the bus connector:
1. Plug the bus connector into the IM 153-x.
2. Screw the bus connector tight on the IM 153-x.
3. If the bus connector is at the beginning or the end of a segment, you must
connect the terminating resistor (switch position ON).
Alternatively, you can use the PROFIBUS terminator as an active bus
terminating element.
4. Lay the interconnecting cable(s) to the designated area for the IM 153-x,
placing it (them) to the right of the 24 V DC terminal.
The nodes with a terminating resistor must always be supplied with voltage during
power-up and operation.
