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 EN61000-3-12
• 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 board.
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.
Use the specified wire type and
connect it securely.
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.
CAUTION
• When connecting the connection
wires to the terminal board using a
single core wire, be sure to perform
curling.
Problems with the work may cause
heat and fires.
3) Pull the wire and make sure that it does not disconnect. Then fix the wire in place with a wire stop.
