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%. Make sure that the voltage imbalance between the phases is 2% or less.

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.

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.

Depending on the importance of the system, separate the power supply system or take protective coordination of breakers.
