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 2 and 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.
