NX-series PROFINET Coupler Unit User’s Manual (W623)
A Unit that has a ground terminal also has a DIN Track contact plate on the back of the Unit.
The DIN Track contact plate is connected internally to the ground terminal on the Unit.
This means that the ground terminal will be electrically connected to the DIN Track.
For information on the DIN Track contact plate on the PROFINET Coupler Unit, refer to
on page 4-12. For information on the NX Units that have a ground terminal, refer to the
NX-series System Units User’s Manual
(Cat. No. W523).
This section describes how to ground the ground terminals on the Profinet IO Device Terminal.
The functional ground terminals that are provided on some Units and the DIN Track are grounded.
