Electrical Connection

You require the EMC filter module order number C73451-A430-D23 for the
electrical connection. The SIPART PS2 positioner supplies power to the
NCS via the EMC filter module. Proceed as follows to connect the shielded
four-pole cable of the NCS to the SIPART PS2 positioner:
1. Replace the dummy stopper on the SIPART PS2 positioner with the
sxcre-type cable gland supplied with the EMC filter module.
NOTE
Use the blue screw-type cable gland for Ex devices and the gray gland for
non-Ex devices.
2. Lay the stripped NCS-cable from the outside through the opening in the
screw-type cable gland with the two openings into the SIPART PS2
positioner. If you do not need the second opening in the screw-type
cable gland, seal this with the enclosed stopper.
3. Screw on the screw-type cable gland tight.
4. Clamp the colored wires of the cable in the following order (see Figure
8, page 57) to the terminal of the EMC filter module:
− yellow
− green
− white or
black
− brown
5. Connect the terminal end of the cable shield with a screw to the
grounding point of the positioner.
