*1 A breaker with at least 3.0 mm contact separation in each poles shall be provided. Use non-fuse breaker (NF) or earth leakage breaker (NV).
*2 In multi-phase appliances, the colour of the neutral conductor of the supply cord, if any, shall be blue.
<Indoor units> When power is supplied to indoor unit and outdoor unit separately
Total operating current of the indoor unit
F0 = 16 A or less *2
F0 = 25 A or less *2
F0 = 32 A or less *2
Apply to IEC61000-3-3 about max. permissive system impedance.
*1 The Ground-fault interrupter should support inverter circuit.
The Ground-fault interrupter should combine using of local switch or wiring breaker.
*2 Please take the larger of F1 or F2 as the value for F0.
F1 = Total operating maximum current of the indoor units × 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 16)/C}

C : Multiple of tripping current at tripping time 0.01s
Please pick up "C" from the tripping characteristic of the breaker.
<Example of "F2" calculation>
* Condition: PEFY-P·VMS1-E × 4 + PEFY-P·VMA-E × 1, C = 8 (refer to right sample chart)
F2 = 19.8 × 4/8 + 38.0 × 1/8
= 14.65
*3 Current sensitivity is calculated using the following formula.
G1 = { V2 × (Quantity of Type 1)} + {V2 × (Quantity of Type 2)} + ··· + {V2 × (Quantity of Type 16)} + { V3 ×
(Wire length [km])}
G1 Current sensitivity

1. Bear in mind ambient conditions (ambient temperature, direct sunlight, rain water, etc.) when proceeding with the wiring and connections.
2. The wire size is the minimum value for metal conduit wiring. The power cord size should be 1 rank thicker consideration of voltage drops.
Make sure the power-supply voltage does not drop more than 10%.
3. Specific wiring reguirements should adhere to the wiring regulations of the region.
4. Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (design 60245 iec57). For example, use
wiring such as YZW.
5. Install an earth longer than other cables.
