Wiring
WARNING
• Do not use tapped 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.
• 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.
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.
