1. Use dedicated power supplies for the outdoor unit and indoor unit. Ensure OC and OS are wired individually.
. Bear in mind ambient conditions (ambient temperature, direct sunlight, rain water, etc.) when proceeding with the wiring and connections.
. 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%. Make sure that the voltage imbalance between the phases is % or less.
4. Specific 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 flexible cord (design 245 IEC57). For
example, use wiring such as YZW.
. A switch with at least  mm [1/ in] contact separation in each pole shall be provided by the Air conditioner installation.
Warning:
• Be sure to use specified wires for connections and ensure no external force is imparted to terminal connections. If connections are not fixed firmly,
heating or fire 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:
• The breakers for current leakage should support Inverter circuit. (e.g. Mitsubishi Electric's NV-C series or equivalent). If no earth leakage breaker is
installed, it may cause an electric shock.
• Breakers for current leakage should combine using of switch.
• Do not use anything other than a breaker with the correct capacity. Using a breaker of too large capacity may cause malfunction or fire.
• If a large electric current flows due to malfunction or faulty wiring, earth-leakage breakers on the unit side and on the upstream side of the power supply
system may both operate.
Depending on the importance of the system, separate the power supply system or take protective coordination of breakers.
