1. Use dedicated power supplies for the outdoor unit and indoor unit. Ensure OC and OS are wired individually.
2. Bear in mind ambient conditions (ambient temperature,direct sunlight, rain water,etc.) when proceeding with the wiring and connections.
3. The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one rank thicker in diameter.
Make sure the power-supply voltage does not drop more than 10%.
4. Specifi c wiring requirements should adhere to the wiring regulations of the region.
5. Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed fl exible cord (design 245 IEC57). For
example, use wiring such as YZW.
6. A switch with at least 3 mm [1/8 in] contact separation in each pole shall be provided when the Air Conditioner is installed.
Warning:
•
Be sure to use specifi ed wires for connections and ensure no external force is imparted to terminal connections. If connections are not fi xed fi rmly,
heating or fi re may result.
•
Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
Caution:
•
A breaker for current leakage must be attached to the power supply. If no earth leakage breaker is installed, it may cause an electric shock.
•
Do not use anything other than a breaker and fuse with the correct capacity. Using a fuse or wire of too large capacity may cause malfunction or fi re.
