Power supply wire and communication wires specifications
Power supply wire and communication wires are procured locally.
For the power supply specifications, follow to the following table. If capacity is little, it is dangerous because
overheat or burnout may be caused.
For specifications of the power capacity of the outdoor unit and the power supply wires, refer to the
Installation Manual attached to the outdoor unit.
Indoor unit power supply
• For the power supply of the indoor unit, prepare the exclusive power supply separated from that of the
outdoor unit.
• Arrange the power supply, circuit breaker, and main switch of the indoor unit connected to the same
outdoor unit so that they are commonly used.
• Power supply wire specification: Cable 3-core 2.5 mm²,
in conformity with Design 60245 IEC 57
.

Power supply
Control wiring, Central controller wiring
• 2-core with polarity wires are used for the Control wiring between indoor unit and outdoor unit and Central
controller wiring.
• To prevent noise trouble, use 2-core shield wire.
• The length of the communication line means the total length of the inter-unit wire length between indoor
and outdoor units added with the central control system wire length.

Communication line
Wired remote controller wiring
• 2-core with non-polarity wire is used for wiring of the remote controller wiring and group remote
controllers wiring.
