9. Attach the WAGO connector to the PCB.
[LAN cable and external KP signal cable wiring]
10. Connect the LAN cable to the LAN connector.
As shown in the above figure, make a loop in the cable (approx. 10mm diameter), then connect the
cable.
11. Fasten the seal nut to fix the transducer cable.
The torque shall be 2.0 Nm and the gap between the seal nut and the super gland shall be approx. 3
mm.
12. Fabricate the external KP signal cable as shown below. (core size 0.75 sq, outer dia 7.6 approx.)
13. Pass the cable through the seal nut and seal assembly, like you did with the transducer cable.
14. Push the seal assembly into the seal nut, then tighten the super gland.
15. Remove the WAGO connector from the PCB and connect it to the external KP signal cable.
16. Connect WAGO connector to the PCB.
17. Tighten the seal nut to fasten the cable.
18. Attach the EMI core (GRFC-8, supplied) to the power cable near the super gland to prevent noise (see
figure below).
19. Attach the ground wire (IV-1.25sq, local supply) to the ground terminal with a crimp-on lug (M3, local
supply) to prevent interference.
20. Reattach the chassis cover.
21. Reattach the cover.
