Wiring
• Do not turn ON the safety breaker until all work is completed.
1)
Strip the insulation from the wire (20mm).
2) Connect the connection 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.
3) Pull the wire and make sure that it does not disconnect. Then fix the wire in place with a wire stop.
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.
1) Do not use tapped wires, stranded wires, extensioncords, 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.
When connecting the connection wires to the terminal board using a single core wire, be sure to perform curling.
Problems with the work may cause heat and fires.
