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 it must be used an earth leak detector capable handling harmonics 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 EN/IEC 61000-3-12

(1)

• Do not turn ON the safety breaker until all work is completed.

1) Strip the insulation from the wire (20mm).
2) Connect the inter-unit wire 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. 

Appearance of outdoor units may differ from some models.

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