Between Indoor and Master Outside unit
The GND terminal at the
main PCB is a ‘-’ terminal
for day contact, it is not
the point to make ground
connection.
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. Run-
ning the product in reversed phase may break the compressor and
other parts.

Between Indoor and Master Outside 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 outside unit s
are matched.(A-A,B-B)
