6. Electric Characteristics
1. Use a separate power supply for the Outside Unit and Indoor Unit.
2. 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%.
3. Specific wiring requirements should adhere to the wiring regulations of the region.
4. Power supply cords of parts of appliances for outside use should not be lighter than polychloroprene sheathed flexible cord.
5. Don't install an individual switch or electrical outlet to disconnect each of indoor unit separately from the power supply.
WARNING
• Follow ordinance of your governmental organization for technical standard related to electrical equipment, wiring regu-
lations 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 con-
nections 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.
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.
