NOTE
Use copper supply wire.
Use UL wire rated 600V for the power supply.
Use UL wire rated 300V for the remote control wires and control wires.
CAUTION
The remote control wire (Communication line) and AC 208/230V wires cannot be parallel to contact each other
and cannot be stored in the same conduits. If doing so, a trouble may be caused on the control system due to
noise or other factor.

Wire connection

REQUIREMENT
Be sure to connect the wires matching the terminal numbers. Incorrect connection causes a trouble.
Be sure to pass the wires through the bushing of wiring connection port of the indoor unit.
Keep a margin (Approx. 3.9" (100 mm)) on a wire to hang down the electrical control box at servicing, etc.
The low-voltage circuit is provided for the remote controller. (Do not connect the high-voltage circuit)
MOCP
Make a loop on the wire for margin of the length so that the electrical control box can be taken out during
(A) servicing.

1. Remove the screws of the terminal cover and take off.
15 2. Remove the screw of the electrical control box cover, and detach the eletrical control box cover by slide.
(The electrical control box cover is clamped onto the hinge)

3. Connect the power supply wire and remote controller wire to the terminal block of the electrical control box.
4. Tighten the screws of the terminal block, and fix the wires with cord clamp attached to the electrical control box.
(Do not apply tension to the connecting section of the terminal block.)
5. Mount the electrical control box cover without pinching wires.
(Mount the cover after wiring on the ceiling panel.)
