C : Multiple of tripping current at tripping time 0.01 second
Please pick up "C" from the tripping characteristic of the breaker.
<Example of "F2" calculation>
* Condition PEFY-NMSU × 4 + PEFY-NMAU-E3 × 1, C = 8 (refer to right sample chart)
F2 = 19.8 × 4/8 + 38 × 1/8
= 14.65
→ 16 A breaker (Tripping current = 8 × 16 A at 0.01 second)
*3 Current sensitivity is calculated using the following formula.
G1 = V2 × (Quantity of Type1) + V2 × (Quantity of Type2) + V2 × (Quantity of Type3) + ... + V2 × (Quantity of Type14)
+ V3 × (Wire length [km])

1. Use a separate power supply for the outdoor unit and indoor unit.
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. 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%.
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 60245 IEC57). For exam-
ple, use wiring such as YZW.
6. Install an earth longer than other cables.
Warning:
Be sure to use specified wires to connect so that no external force is imparted to terminal connections. If connections are not fixed firmly, it may cause
heating or fire.
Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
Be sure to attach the terminal block covers/panel of the outdoor unit securely.
If it is not attached correctly, if could result in a fire or an electric shock due to dust, water. etc.
Caution:
Be careful not to make mis-wiring.
Firmly tighten the terminal screws to prevent them from loosening.
After tightening, pull the wires lightly to confirm that they not move.
If the connecting wire is incorrectly connected to the terminal block, the unit does not operate normally.
Some installation site may require attachment of an earth leakage breaker. If no earth leakage breaker is installed, it
may cause an electric shock.
Do not use anything other than breaker and fuse with correct capacity. Using fuse and wire or copper wire with too
large capacity may cause a malfunction of unit or fire.
Properly route wiring so as not to contact the sheet metal edge or a screw tip.
