Between Indoor and Outdoor unit
The GND terminal at the main PCB is a ‘-’ ter-
minal 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 connec-
tion 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, momentary 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.
