Wiring of Main Power Supply and Equipment Capacity
1. Use a separate power supply for the Outdoor Unit and Indoor Unit.
2. Bear in mind ambient conditions (ambient temperature,direct sunlight, rain liquid,etc.) when proceeding with the
wiring and connections
3. The wire 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%.
4. Specific wiring requirements should adhere to the wiring regulations of the region.
5. Power supply cords of parts of appliances for outdoor use should not be lighter than polychloroprene sheathed
flexible cord (design 60245 IEC57).
6. Don't install an individual switch or electrical outlet to disconnect each of indoor unit separately from the power
supply.
WARNING
• Follow ordinance of local regulation for technical standard related to electrical equipment, wiring
regulations and guidance of each electric power company.
• Make sure to use specified wires 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 generated overcurrent
may include some amount of direct current.
• Installation site must require attachment of an earth leakage breaker. If no earth leakage breaker is
installed, it may cause an electric shock.
CAUTION
• 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.
