Connection
5.2 Electrical wiring
Procedure
The NCS sensor is equipped with a shielded four-pole cable. Wire this cable to the positioner
as follows:
1. Feed the four-pole NCS cable
type of cable gland depends on the positioner version.
2. Tighten the cable gland
3. Terminate the four-pole NCS cable
diagram.
4. Place the cable clamp
5. Use the screw
ground terminal of the positioner.
6. Grounding:
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.
