・Be sure to use the appropriate type of circuit breaker. Note that generated overcurrent may include some amount of
direct current.
・Select the type of breaker for an inverter circuit as an earth leakage circuit breaker. (Mitsubishi Electric NV-S series
or its equivalent)
・The earth leakage circuit breaker should be used in combination with a local switch.
・Ensure the correct phase sequence. (L1, L2, and L3)
・If the power cable is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
・Use dedicated power cables for the outdoor unit and indoor unit. Ensure OC and OS are wired individually.
・Power cable size, device capacity, and system impedance
(If local regulations do not specify the minimum power cable size or device capacity, follow the values in the table
below.)
