Wiring

 WARNING

• Do not use tapped wires, stranded wires, extension cords, or starburst connections, as they may cause overheating, 

electrical shock, or fire.

• 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.

• Be sure to install an earth leak detector. (One that can handle higher harmonics.)

(This unit uses an inverter, which means that an earth leak detector capable of handling higher harmonics must be used, in 
order to prevent malfunctioning of the earth leak detector itself.)

• Use an all-pole disconnection type breaker with at least 3mm between the contact point gaps.
• Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.

• Equipment complying with EN61000-3-12

(1)

• 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. The 
screws are packed with the terminal block.

NOTE

(1)

European/International Technical Standard setting the limits for harmonic currents produced by equipment connected to public 
low-voltage systems with input current >16 A and 

75 A per phase.

Observe the notes mentioned below when wiring to the power supply terminal block.
Precautions to be taken for power supply wiring.

 CAUTION

• When connecting the wires to the terminal block using a single core 

wire, be sure to perform curling.
Problems with the work may cause heat and fires.  

• If the stranded wires must be used, make sure to use the round 

crimp-style terminal for connection to the power supply terminal 
block. Place the round crimp-style terminals on the wires up to the 
covered part and secure in place.

3) Pull the wire and make sure that it does not disconnect. Then fix the wire in place with a wire stop.
