Make a knockout hole by driving in a nail.
After making a knockout hole, apply rust resisting paint around
the hole.
When installing the cables through the knockout hole, remove all
burrs and protect them with the protection tape.
CAUTION
Be sure to run the power supply cable and the communication cable through electrical conduit
as seen in the picture.
Install the communication cable, indoor power cable and the main power cable in the cable tube.
Secure the cable tube to the outdoor knockout using the CD connector and bushing.
Arrange the cables as shown in the picture.
The diameter of the 6 knock-out holes is
Ø
27.8 mm.

Communication cable
between indoor and
outdoor units
Connect the power cable of the outdoor unit after checking that L1-L2-L3-N(3 phase 4 wire) is properly connected.
(If 380V power cable is connected to N phase, PCB or other components may be damaged.)
The communication cable between indoor and outdoor units has no polarity.
Secure the cables using the clamp of the electrical component box of the outdoor unit.

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.
