Electrical Connections (Continued)

You should connect the power cable into the power cable terminal and fasten it with a
clamp.

The unbalanced power must be maintained within 2% of supply rating.
- If the power is unbalanced greatly it may shorten the life of the condenser.
If the unbalanced power is exceeded over 4% of supply rating, the indoor unit is
protected, stopped and the error mode indicates.

To protect the product from water and possible shock, you should keep the power cable
and the connection cord of the indoor and outdoor units in the iron pipe.

Connect the power cable to the auxiliary circuit breaker. An all pole disconnection
from the power supply must be incorporated in the fixed wiring(≥3mm).

Must keep the cable in a protection tube.

Keep distances of 50mm or more between power cable and communication cable.

Power cable should be used within maximum length limitation.

Each indoor unit power should be supplied between maximum and minimum values.

The power cable is not supplied with the air conditioner.

For the power cable, use the grade H07RN-F or H05RN-F materials.
