Example) Connection of communication cable

[BUS type]

[STAR type]

- Connection of communication

cable must be installed like
below figure between indoor
unit to outdoor unit.

- Abnormal operation can be

caused by communication
defect, when connection of
communication cable is installed
like below figure(STAR type).

It should be wiring power cables or communication cables to avoid
interference with the oil level sensor. Otherwise, That oil level sensor
would be operated abnormally.

Example) Connection of power and communication cable (UXA)
