10-3.Remote Controller Wiring
• Strip off approx. 9 mm the wire to be connected.
• For single system, use non polarity, 2 core wire is used for wiring of the remote controller.
(0.5 mm² to 2.0 mm² wires)
• For the synchronous twin system, use 2-conre shield wire (Vinyl cord for microphone 0.5 to 2.0 mm²) to conform
to the EMC standard.
* Use 2-core shield wire (MVVS 0.5 to 2.0 mm² or more) for the remote controller wiring in the simultaneous twin
simultaneous triple and simultaneous double twin systems to prevent noise problems.
Be sure to connect both ends of the shield wire to earth leads.
* Connect earth wires for each indoor unit in the simultaneous twin simultaneous triple and simultaneous double
twin system.
