The rear steel panel of the NCS sensor is inevitably bonded to the ground potential of the system when mounting on the
console. This ground connection is only functional if there is a low-impedance connection to ground potential of the
system. Ensure this state by measuring the ground resistance. If necessary, ensure proper grounding by means of an
additional cable from the NCS sensor to ground potential.

Connecting the external position detection system to the EMC filter module
Requirement
You need the EMC filter module with article number C73451-A430-D23 for the electrical connection of an external position
detection system, article number C73451-A430-D78, to the positioner.
