▼ 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
Remote controller wiring
• 2-core with non-polarity wire is used for wiring of the remote controller wiring and group remote controllers wiring.
CAUTION
The remote controller wire (Communication line) and AC 220 – 240 V 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 or other factor.
Power supply
220 V – 240 V ~, 50 Hz
220 V ~, 60 Hz
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.
