Wiring

WARNING
• Do not use tapped wires, extension cords, or starburst connections, as they may cause overheating, electrical shock, or fi re.
• 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 fi re.
• 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 harmonics must be used in order to
prevent any malfunction of the earth leak detector itself.)
• Use an all-pole disconnection type circuit breaker with at least 3mm between the contact point gaps.
• The earth leakage circuit breaker must operate at 30mA or lower.
• Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fi re.
• Do not turn on the circuit breaker until all work is completed.
1) Strip the insulation from the wire (20mm).
2) Connect the inter-unit wires between the indoor and outdoor units so that the terminal numbers match. Tighten the terminal
screws securely. We recommend a fl athead screwdriver be used to tighten the screws. The screws are packed with the terminal
block.
Firmly fi x the wires with the terminal screws.
Firmly secure wire retainer
so wire terminations will
not receive external stress.
Use the specifi ed wire type
and connect it securely.
CAUTION
• When using stranded wires, make sure to use a
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.
• Use the following method when installing a round crimp-style terminal.
