6WIRING EXAMPLE AND HOW TO SET THEREMOTE CONTROLLERHow to connect wiring (see figure 13)• Power supply wiringRemove the switch box lid (1) and connect the wires to thepower supply terminal board inside. While doing this, pull thewires inside through the rubber bush A and clamp the wiresalong with other wires using clamp A, untightening the clip ofclamp A by pressing. After the connection, tighten clamp A asbefore.• Unit wiring and remote controller wiringRemove the switch box lid (2) and pull the wires insidethrough the rubber bush B and connect to the terminal boardfor unit transmission wiring.• After connectionAttach the small sealing (supplied with the unit) around thecables to prevent infiltrating of water from the outside into theunit. If two or more cables are used, divide the small sealinginto the required number of pieces and wrap them around allthe cables.1 Switch box lid (1)2 Power supply3 Power supply terminal board4 Rubber bush A5 Clamp A6 Switch box lid (2) with wiring diagram label7 Transmission wiring8 Terminal board for transmission wiring9 Rubber bush B10 Clamp B11 Outside of the unit12 Inside of the unit13 Cable (power supply or transmission wiring)14 Opening for the cable15 Small sealingPRECAUTIONS1 Observe the notes mentioned below when wiring to the powersupply terminal board.• Do not connect wires of different gauge to the same powersupply terminal. (Looseness in the connection may causeoverheating.)• When connecting wires of the same gauge, connect themaccording to the figure.Use the specified electric wire. Connect the wire securelyto the terminal. Lock the wire down without applyingexcessive force to the terminal. (Tightening torque:131Ncm ±10%).2 Keep total current of crossover wiring between indoor unitsless than 12A. Branch the line outside the terminal board ofthe unit in accordance with electrical equipment standards,when using two power wiring of a gauge greater than 2mm 2(Ø1.6).The branch must be sheathed in order to provide an equal orgreater degree of insulation as power supply wiring itself.3 Do not connect wires of different gauge to the samegrounding terminal. Looseness in the connection maydeteriorate the protection.4 Remote controller cords and wires connecting the unitsshould be located at least 50mm away from power supplywiring. Not following this guideline may result in malfunctiondue to electrical noise.5 For the remote controller wiring, refer to the "Installationmanual of the remote controller" supplied with the remotecontroller.NoteThe customer has the ability to select the remote controllerthermistor (only for FHYCP35~125B7V1).6 Never connect the power supply wiring to the terminal boardfor transmission wiring. This mistake could damage the entiresystem.7 Use only specified wires and tightly connect wires to theterminals. Be careful that wires do not place external stresson the terminals. Keep wiring in neat order so that they do notobstruct other equipment such as popping open the servicecover. Make sure the cover closes tight. Incompleteconnections could result in overheating, and in the worsecase, electric shock or fire.WIRING EXAMPLEFor the wiring of outdoor units, refer to the installation manualattached to the outdoor units.Confirm the system type:• Pair type: 1 remote controller controls 1 indoor unit (standardsystem).• Simultaneous operation system: 1 remote controller controls2 indoor units (2 indoor units operate equally)• Group control: 1 remote controller controls up to 16 indoorunits (All indoor units operate according to the remotecontroller).• 2 remote controller control: 2 remote controllers control 1indoor unit.Pair type (figure 15)Simultaneous operation system (figure 16)Group control (figure 17)2 remote controller control (figure 18)1 Main power supply2 Main switch3 Fuse4 Outdoor unit5 Indoor unit6 Remote controller (optional accessories)7 Indoor unit (Master)8 Indoor unit (Slave)NOTE• It is not necessary to designate indoor unit address whenusing group control.
