5-4. Important Note When Wiring for Common 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.

2.Connect the power supply wires to "L1, L2" of the terminal block. Be sure to connect the grounding conductor of the incoming power supply to the earth (ground) screw.

3.Securely affix the power supply wires and remote control wires by the clamping strap or clamping clip not to cross each other and not to leave the wirings loose. When loosening the clamping clip, twist the strap and it will come undone.
