C : Multiple of tripping current at tripping time 0.01s
Please pick up "C" from the tripping characteristic of the breaker.
F2 = 19.8 × 4/8 + 38 × 1/8
= 14.65
* 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 Type4) + V2 × (Quantity of Others) + V3 × (Wire length [km])

1. Use a separate power supply for the outdoor unit and indoor unit.
. Bear in mind ambient conditions (ambient temperature,direct sunlight, rain water,etc.) when proceeding with the wiring and connections.
3. The wire si e is the minimum value for metal conduit wiring. The power cord si e should be 1 rank thicker consideration of voltage drops.
Make sure the power-supply voltage does not drop more than 10%.
. Speci c wiring requirements should adhere to the wiring regulations of the region.
. Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed e ible cord (design 60
ple, use wiring such as YZW.
6. Install an earth longer than other cables.
Warning:
Be sure to use speci ed wires to connect so that no e ternal force is imparted to terminal connections. If connections are not
heating or re.
Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
Caution:
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 re.
IMPORTANT
Make sure that the current leakage breaker is one compatible with higher harmonics.
Always use a current leakage breaker that is compatible with higher harmonics as this unit is equipped with an inverter.
The use of an inadequate breaker can cause the incorrect operation of inverter.
