Warning:
• Please turn off the main power supply when servicing. And do not touch the B1, B2
terminals when the power is energized. If isolator should be used between outdoor
unit and branch box/indoor unit and branch box, please use 3-pole type or 2-pole type.
(Please refer to figure below.)
• Turn on the main power when the ambient temperature is -20°C (-4°F) or higher.
• Under conditions of -20°C (-4°F), it needs at least 4hr stand by before the units
operate in order to warm the electrical parts.
Caution:
After using the isolator, be sure to turn off and on the main power supply to reset the system. Otherwise, the outdoor unit may not be able to detect the branch
box(es) or indoor units.
Be sure to connect the outdoor-branch box/indoor-branch box connecting cables directly to the units (no intermediate connections).
Intermediate connections can lead to communication errors if water enters the cables and causes insufficient insulation to ground or a poor electrical contact at the intermediate connection point.
(If an intermediate connection is necessary, be sure to take measures to prevent water from entering the cables.)
Never splice the power cable or the indoor-outdoor-branch box connection cable, otherwise it may result in a smoke, a fire or communication failure.

*1. Please follow applicable federal, state, or local codes to prevent potential leakage/electric shock. Or install a ground fault interrupt for the prevention of leakage and
electric shock.
IMPORTANT
If a current leakage breaker is used, it should be 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.
*2. Use copper supply wires. Use the electric wires over the rating voltage 300 V.

The Ground-fault interrupter should combine using of local switch or wiring breaker.

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.
