Between Indoor and Master Outdoor unit

The GND terminal at the main PCB is a ‘-’ terminal for dry contact.

It is not the point to make ground connection.

- Make sure that terminal number of master and slave outdoor units

are matched.(A-A,B-B)

WARNING

• Indoor Unit ground wires are required for preventing electrical

shock accident during current leakage, Communication disorder by
noise effect and motor current leakage (without connection to pipe).

• Don't install an individual switch or electrical outlet to disconnect

each of indoor unit separately from the power supply.

• Install the main switch that can interrupt all the power sources in an

integrated manner because this system consists of the equipment
utilizing the multiple power sources.

• If there exists the possibility of reversed phase, lose phase, mo-

mentary blackout or the power goes on and off while the product is
operating, attach a reversed phase protection circuit locally.
Running the product in reversed phase may break the compressor
and other parts.

!

CAUTION

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.
