Connection of wiring between units, ground wire and for the remote control cord (Refer to Fig. 29)
• Wiring between units and ground wire
Remove the control box lid and connect wires of matching number to the power supply terminal block
(4P)inside. And connect the ground wire to the terminal block. In doing this, pull the wires inside through
the hole and fix the wires securely with the included clamp (4).
• Give enough slack to the wires between the clamp (4) and power supply terminal block. (Use Fig. 30 as a
guide and allow at least 80mm for removing the sheath.)
• Remove the control box lid and pull the wires inside through the hole and connect to the terminal block for
remote controller (6P). (no polarity) Securely fix the remote controller cord with the included clamp (4).
• Give enough slack to the wires between the clamp (4) and the terminal block for the remote controller.
• After connection, attach sealing material (12)
• Be sure to attach it to prevent the infiltration of water from the outside.
