14 Wiring instructions for remote core processor with remote transmitter There are two phases to this procedure: • W iring the remote core pr ocessor to the transmitter • W iring the sensor to the remote core processor T o wire the remote core processor to the tr ansmitter: 1. Use one o f the followin g me thods to shield the wiring: • If you[...]

15 4. For connection at the core processo r housing , prepare shielded c able as follo ws (for armored cable, omit steps d, e, f, g): a. Strip 4 1/2 inches (114 mm ) of cable jacket. b . Remo ve the clear wrap that is inside the cable jacket, and remo ve the f iller material between the wires. c. Remov e the foil shield that is ar ound the insulate[...]

16 g. Position gland clamping insert so the interior end is flush with the heat shrink. h. Fold the cl oth shield or braid and drain wires over the clamping insert and approximately 1/8 in ch (3 mm) past the O-ring. i. Install the gland body into th e core processor housing conduit opening. 5. Insert the wires thro ugh the gland body and assemble t[...]

17 7. Reinstall and tighten the core processor lid. 8. T o connect the cable to the transm itter , connect the four wires from the core processor to the appropriate terminals on the transmitter . See T able 3 and Figure 13. No bare wires should remain e xposed. Do not ground the shield or drain wire(s) at the transmitter . T o wire the sensor to th[...]
