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 a ground fault circuit interrupter breaker. (One that can handle higher harmonics.)
(This unit uses an inverter, which means that it must be used a ground fault circuit interrupter breaker capable handling
harmonics in order to prevent malfunctioning of the ground fault circuit interrupter breaker itself.)
• Use an all-pole disconnection type breaker with at least 1/8 inch (3mm) between the contact point gaps.
• When carrying out wiring connection, take care not to pull at the conduit.
• 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 (3/4 inch
(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
board.
<Work before wiring>
A protection plate is fixed for protection from the high-voltage section.
Before staring wiring work, dismount the protection plate by removing the 2 screws and dismount the conduit mounting plate cover
by removing the 1 screw.
<Method of mounting conduit>
1) Pass wires through the conduit and secure them with a lock nut.
2) After completing the work, reattach the conduit mounting plate cover and the protection plate to its original position.
Observe the notes mentioned following 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.
Place the round crimp-style terminals on the wires up to the covered part
and secure in place.
