Static Discharge in Long PROFIBUS DP Cables

Static Discharge in Long PROFIBUS DP Cables

Static Discharge Very long bus cables, which have been laid but not yet connected, are discharged as follows:

Step Action

1 Select the PROFIBUS DP connector closest to the FE/PE grounding clamp. 2 Touch the metal of the connector housing to the cabinet's FE/PE grounding clamp to discharge any static electricity.

3 Now connect the bus connector to the device.

4 Discharge the other PROFIBUS DP cable connectors as described in steps 2and 3.

Notes

NOTE: During mounting, the metal part of the PROFIBUS DP connector is connected internally to the cable shield. When the bus cable connector is inserted into the module’s PROFIBUS port, a short connection between the shield and the FE/PE is created automatically.
