Power supply
Power supply switch / circuit 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
• 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
TU2C-Link models (U series) can be combined with TCC-Link models (other than U series).
