Power supply wire and communication wires specifi cations
Power supply wire and communication wires are procured locally.
For the power supply specifi cations, follow the table below. Power supply wiring and communication wiring are to be
procured locally.
For specifi cations of the power capacity of the outdoor unit and the power supply wires, refer to the Installation Manual
supplied with the outdoor unit.
Indoor unit power supply
• Prepare an exclusive power supply for the indoor unit independently of the outdoor unit.
• Arrange the power supplies to the indoor and outdoor units, so that a common earth leakage breaker and main
switch can be used.
• Power supply wire specifi cation: Cable 3-core 2.5 mm
▼ Power supply
Power supply
Power supply switch/Earth leakage breaker or power supply wiring/fuse rating for indoor units should be selected by the accumulated
total current values of the indoor units.
Power supply wiring
Control wiring, Central controller wiring
• Use a 2 core non polarity wire.
• To prevent any possible noise issues, use a shielded 2 core wire.
• The total stated length of communication wiring is determined by the interconnecting length of indoor to outdoor
wire plus the length of the central control communication wire.

Control wiring between indoor units, and outdoor unit
(2-core shield wire)
Central control line wiring (2-core shield wire)
Wired remote controller wiring
This wiring is not required when using the supplied wireless remote controller.
• For wiring remote controllers a 2 core non polarity wire must be used.
Wired remote controller wiring, remote controller inter-unit wiring
Total wire length of wired remote controller wiring and remote controller
inter-unit wiring = L + L1 + L2 + ... Ln
Total wire length of wired remote controller inter-unit wiring = L1 + L2 + ... Ln
The remote controller wire (Communication line) and AC220–240V wires cannot be parallel to contact each other
and cannot be stored in the same conduits. If doing so, a trouble may be caused on the control system due to noise,
etc.
