Electric wiring and the application
The outdoor and all indoor units are in parallel through 2 non-polar wires.
Three wiring methods between wired controller and indoor unit:
indoor 2 is wired control master unit, the others are wired control slave units. Wired controller and the master indoor
(directly connected to wired controller) is connected by 3 polar wires; the other indoors and the master indoors are
connected by 2 polar wires.
controller are connected by 3 polar wires.
set as master wired controller, and the other is slave wired controller. Master/slave wired controller, and master/indoor
are connected by 3 polar wires.
When indoor is controlled by remote controller, refer to the "wired control master unit/wired control slave unit/remote
control unit table".A, B, C on signal terminal block need not wires and not connect the wired controller.

power source: 1PH, 220-240V~, 50/60Hz
Indoor and outdoor use their individual power source. All indoors use one power source. Must install the leakage breaker
and the over current breaker, or electric shock will occur.

•
• To avide electrical shock, make sure to disconnect the power supply 1 minute or more before servicing the electrical
parts.Even after 1 minute,always measure the voltage at the terminals of main circuit capacitors or electrical parts and
before touching, make sure that those voltages are 50VDC or less.
• To persons in charge of electrical wiring work: Do not oerate the unit until the refrigerant piping is complete. (Running
it before the piping is ready will break the compressor)
• Each outdoor must be earthed well.
