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 power supply 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.
