8 ELECTRICAL CONNECTION

WARNING

1.Using the specified wires, ensure to connect the wires, and fix wires securely so that the external tension to the wires do not affect the connecting part of the terminals.

Incomplete connection or fixation may cause a fire, etc.

2.Be sure to connect earth wire. (grounding work)

Incomplete grounding cause an electric shock. Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.

3.Appliance shall be installed in accordance with national wiring regulations.

Capacity shortage of power circuit or incomplete installation may cause an electric shock or a fire.

Remote controller wiring

2-core non polarity wire is used for the remote controller wiring.

Wiring

1.Figure below shows the wiring connections indoor power line and between the indoor and outdoor units and between the indoor units and remote controller. The wires indicated by the dash lines are provided at the installation place.

2.Insulate the unsheathed redundant cords (conductors) with electrical insulation tape.

Process them so that they do not touch any electrical or metal parts.

CAUTION

•If incorrect/incomplete wiring is carried out, it will cause an electrical fire or smoke.

•Be sure to install an earth leakage breaker that is not tripped by shock waves.

If an earth leakage breaker is not installed, an electric shock may be caused.

•Be sure to use the cord clamps attached to the product.

•Do not damage or scratch the conductive core and inner insulator of power and inter-connecting wires when peeling them.

•Use the power cord and Inter-connecting wire of specified thickness, type, and protective devices required.

REQUIREMENT

•	For power supply wiring, strictly conform to the Local
	Regulation in each country.
•	Power supply for indoor unit must be exclusive and
	separated from the one for outdoor unit.

• For wiring of power supply of the outdoor units, follow the

Installation Manual of each outdoor unit.

• Never connect 220–240V power to the terminal blocks

( A , B , etc.) for control wiring.

(Otherwise, the system will fail.)

• Perform the electric wiring so that it does not come to

contact with the high-temperature part of the pipe.

The coating may melt resulting in an accident.

• After connecting wires to the terminal blocks, provide a

trap and fix wires with the cord clamp.

• Run the refrigerant piping line and control wiring line in

the same line.

• Do not turn on the power of the indoor unit until

vacuuming of the refrigerant pipes completes.
