Installation
Bus terminating resistors | The first and last station in a bus segment must be connected |
| to the bus with the bus terminating resistor switched on. The |
| bus terminating resistor is switched externally. This external |
| switch function can either be implemented as a separate bus |
| terminating resistor or with a special |
| integrated bus termination. |

EMC wiring | Electromagnetic interference may have adverse effects on the |
| communication fieldbus. This can be minimized in advance by |
| taking suitable EMC measures. These include: |
| • System design in accordance with EMC requirements, |
| • EMC cabling and |
| • Measures that prevent the occurrence of large potential |
| differences, |
| • Correct installation of the PROFIBUS system (cable, |
| connection of bus connector,...). |
| The effects of electromagnetic interference can be |
| significantly reduced by fitting the shield. The following two |
| figures illustrate how to fit the shield. |
