WIRING

To prepare the cable for sensor wiring:

1.Use only the cable specified. Figure 3-4 shows the 10 conductor cable with 3 shields (9200273).

2.Strip back the PVC jacket 4 in. or far enough to access the eleven screw terminals in the junc- tion box, or the eleven terminals in the con- troller. Separate the two coaxial cables and pre- pare each as follows:

2a. Strip back the insulating black sheath about 1½ in.

2b. Separate the braid from the inner black conductive sheath.

2c. Solder an insulated wire to the braid.

2d. Strip the black conductive sheath 1 in. to expose the colored (orange or gray) cable inside.

FIGURE 3-4. Cable Dressing

2e. Insulate the exposed black sheath and braid area to prevent shorts.

3.Strip ¼ in. of insulation on each conductor for terminal mounting. Insulate the exposed foil shields with heat shrink sleeves or electrical tape. Be sure that heat shrink overlaps the exposed metal end where the foil shield has been cut. Shields must not be shorted together. The sensor will not work if foil shields or drain wires are not electrically isolated from each other.
