Installation and operation manual7 FXSQ20~140P7VEBVRV System air conditioners4PW56483-1Specifications for field supplied fuses and wireAllowable length of transmission wiring between indoor and outdoorunits, and between the indoor unit and the remote controller is asfollows:1. Outdoor unit - indoor unit: max. 1000 m (total wiring length:2000 m)2. Indoor unit - remote controller: max 500 mWIRING EXAMPLE AND HOW TO SET THEREMOTE CONTROLLERHow to connect wiringRemove the switch box cover as shown in figure 12, and make theconnections.PRECAUTIONS1 Observe the notes mentioned below when wiring to the powersupply terminal board.- Use a round crimp-style terminal for insulation sleeve forconnection to the terminal block for wiring the units. Whennone are available, follow the instructions below.- 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 securely to theterminal. Lock the wire down without applying excessive force tothe terminal. Use torques according to the table below.- When attaching the control box lid, make sure not to pinchany wires.- After all wiring connections are done, fill in any gaps in thecasing wiring holes with putty or insulation material (fieldsupply) thus to prevent small animals or dirt from entering theunit from outside and causing short circuits in the control box.2 Keep total current of crossover wiring between indoor units lessthan 12 A. Branch the line outside the terminal board of the unitin accordance with electrical equipment standards, when usingtwo power wiring of a gauge greater than 2 mm 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 same groundingterminal. Looseness in the connection may deteriorate theprotection.4 Remote controller cords and wires connecting the units shouldbe located at least 50 mm away from power supply wiring. Notfollowing this guideline may result in malfunction due toelectrical noise.5 For the remote controller wiring, refer to the "Installation manualof the remote controller" supplied with the remote controller.6 Never connect the power supply wiring to the terminal board fortransmission 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 stress onthe terminals. Keep wiring in neat order so that they do notobstruct other equipment such as popping open the switch boxcover. Make sure the cover closes tight. Incomplete connectionscould result in overheating, and in the worse case, electric shockor fire.Power supply wiringModel Field fuses Wire Size20~140 16 A H05VV-U3G Local codesModel Wire Size20~140 Sheathed wire (2) 0.75-1.25 mm2NOTE For details, refer to "Wiring example" on page 8.1 Switch box cover2 Transmission wiring port3 Power supply wiring port4 Wiring diagram5 Switch box1 2 31 Round crimp-style terminal2 Attach insulation sleeve3 WiringTightening torque (N•m)Terminal block for unit transmission andremote controller 0.9Terminal block for power supply 1.2
