ENGLISH

- Use a separate power supply for the Outdoor Unit and Indoor Unit.

- Bear in mind ambient conditions (ambient temperature,direct sun-

light, rain water,etc.) when proceeding with the wiring and connec-
tions.

- The cable size is the minimum value for metal conduit wiring. The

power cord size should be 1 rank thicker taking into account the line
voltage drops. Make sure the power-supply voltage does not drop
more than 10%.

- Specific wiring requirements should adhere to the wiring regulations

of the region.

- Power supply cords of parts of appliances for outdoor use should not

be lighter than polychloroprene sheathed flexible cord.

- Don't install an individual switch or electrical outlet to disconnect

each of indoor unit separately from the power supply.

CAUTION

• Some installation site may require attachment of an earth leakage

breaker. If no earth leakage breaker is installed, it may cause an
electric shock.

• Do not use anything other than breaker and fuse with correct ca-

pacity. Using fuse and wire or copper wire with too large capacity
may cause a malfunction of unit or fire.

WARNING

• Follow ordinance of your governmental organization for techni-

cal standard related to electrical equipment, wiring regulations
and guidance of each electric power company.

• Make sure to use specified cables for connections so that no

external force is imparted to terminal connections. If connec-
tions are not fixed firmly, it may cause heating or fire.

• Make sure to use the appropriate type of overcurrent protection

switch. Note that generated overcurrent may include some
amount of direct current.

WARNING

• Indoor Unit ground wires are required for preventing electrical shock ac-

cident during current leakage, Communication disorder by noise effect
and motor current leakage (without connection to pipe).

• Don't install an individual switch or electrical outlet to disconnect

each of indoor unit separately from the power supply.

• Install the main switch that can interrupt all the power sources in an

integrated manner because this system consists of the equipment
utilizing the multiple power sources.

• If there exists the possibility of reversed phase, lose phase, mo-

mentary blackout or the power goes on and off while the product is
operating, attach a reversed phase protection circuit locally. Run-
ning the product in reversed phase may break the compressor and
other parts.

Example) Connection of transmission wire

[BUS type]

[STAR type]

- Connection of communication

cable must be installed like
below figure between indoor
