・
Be sure to use the appropriate type of overcurrent 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 breaker. (Mitsubishi Electric NV-S series or its
equivalent)
・
The earth leakage breaker should be used in combination with a local switch.
・
Use a local switch with at least 3 mm (1/8 in) contact separation in each pole.
・
Do not connect the power cables L1, L2, and L3 to N. Ensure the correct phase sequence.
・
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.)

*1 : Use the larger value of F1 or F2 as the value of F0.
F1 = Total of each indoor unit's maximum current × 1.2
F2 = {V1 × (Quantity of Type 1)/C} + {V1 × (Quantity of Type 2)/C} + {V1 × (Quantity of Type 3)/C} + {V1 × (Quantity of Type 4)/C}
*2 : Current sensitivity is calculated using the following formula.
G1 = (V2 × Quantity of Type 1) + (V2 × Quantity of Type 2) + (V2 × Quantity of Type 3) + (V2 × Quantity of Type 4) +
(V3 × Power cable length (km))
