Figure 9: 9-pol. Connector
For the use of the Profibus version in analog mode is a +/- 15 VDC power supply required. For the
use in digital mode a +/- 15 VDC or a 24 VDC power supply is sufficient. This connector does not
provide a particular pin for connection of the shield to the case. Connect the cable shield to the
connector housing for grounding.
The cable must be equipped with a ferrite (Würth 742 712 21).
