5-5. Important Note When Wiring for XM Type

Connect the wires referring to the diagram. Note that the remote control wires and the power supply wires are not supplied. The remote control wires shall be segregated from the power supply wires as follows:

1.Install the optional remote control wires (field supplied) and the manufacturer supplied 3-way wiring harness to the electrical connection box as shown in the diagram. One end of the optional remote control wiring is connected to the R1/R2 terminals. Then place and fix the two clasps so that the clasps shall cover both the remote control wires and the 3-way wiring harness as shown in the magnified drawing.

2.Connect the grounding conductor of the incoming power supply to the earth (ground) screw before connecting the power supply conductors to "L1, L2" of the terminal block.

3.Securely affix the two power supply conductors (L1, L2) in the wiring channel by the clamping strap as shown.

NOTE

Take care not to damage the remote wiring by the clasp. Do not leave the remote wiring loose.
