After removing the Micro Style or Open Style connection, you
will find a 9−pin Sub−D plug on the top of the field bus node.

Please note
The screening connection at pin 5 of the Sub−D plug is
capacitively connected to the housing within the CPX
terminal. This prevents equalising currents from flowing
via the screening of the field bus cable (see Fig. 1/6).
