ELECTRICAL WIRING

ENGLISH

Wiring of main power supply and equipment capacity

- Bear in mind ambient conditions (ambient temperature,direct sunlight, rain water,etc.) when

proceeding with the wiring and connections.

- The cable size is the minimum value for metal conduit wiring. The power cable 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 cable cords of parts of appliances for outdoor use should not be lighter than polychloro-

prene sheathed flexible cable.

- 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 capacity. 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 technical standard related to elec-

trical 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 connections are not fixed firmly, it may cause heating or fire.

• Make sure to use the appropriate type of overcurrent protection switch. Note that gener-

ated overcurrent may include some amount of direct current.
