Wiring
WARNING
1) Do not use tapped wires, stranded wires, extension cords, or starburst connections, as they may cause overheating, electrical
shock, or fire.
2) Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the
terminal block.) Doing so may cause electric shock or fire.
3) Be sure to install an earth leakage breaker. (One that can handle higher harmonics.)
(This unit uses an inverter, which means that it must be used an earth leakage breaker capable handling harmonics in order to
prevent malfunctioning of the earth leakage breaker itself.)
4) Use an all-pole disconnection type breaker with at least 3mm between the contact point gaps.
5) Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.
• Do not turn ON the power supply until all work is completed.
1) Strip the insulation from the wire (20mm).
2) Connect the connecting wires between the
indoor and outdoor units
so that the terminal
numbers match.
Tighten the terminal screws
securely. We recommend a flathead
screwdriver be used to tighten the screws.
The screws are packed with the terminal
board.
Observe the notes mentioned below when wiring to the power supply
terminal board.
Precautions to be taken for power supply wiring.
Use a round crimp-style terminal for connection to the power supply
terminal board. In case it cannot be used due to unavoidable reasons,
be sure to observe the following instruction.
Place the round crimp-style terminals on the wires up to the
covered part and secure in place.
