Slip the single cable from the load cell or load cell junction box through the gland connectorand into the enclosure.4. Referring to Figure No. 4, remove 3 inches (not 5 to 6 inches) of the outer insulation jacket5. Next, remove 1/4 inch of insulation from each of the 4 wires and shield (without senseleads) or 6 wires and shield (with sense leads).6. Referring to the table below (or on the circuit board) for terminal connections, connect eachof the wires to terminal block P13. Refer to Figure No. 11 for terminal block location.LOAD CELL TERMINAL – (P13)UPIN NO.U UFunctionU UPIN NO.U UFunctionU1 + EXCITATION 5 - SIGNAL2 + SENSE 6 - SENSE3 + SIGNAL 7 - EXCITATION4 SHIELD7. To terminate a wire, use a small flat blade screwdriver and press down on the release barfor the terminal. Insert the wire into the terminal opening. Remove the screwdriver,allowing the release bar to return to its original position, locking the wire in place. SeeFigure No. 5.8. Repeat the procedure until all wires are in place.9.
