ELECTRICAL WIRING
ENGLISH
Wiring of main power supply and equipment capacity
- Use a separate power supply for the Outdoor Unit and Indoor Unit.
- 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.
