While doing this, pull thewires inside through the hole in the casing and clamp the wiresalong with other wires using a clamp as indicated in the figure.■ Unit transmission wiring and remote controller wiringRemove the control box lid (1) and pull the wires inside throughthe hole in the casing and connect to the terminal block for unittransmission wiring (F1, F2) and remote controller wiring(P1, P2). Securely fix the wiring using a clamp as indicated inthe figure.■ 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 sealing intothe required number of pieces and wrap them around all thecables.■ Attach the control box lid.Precautions1 Observe the notes mentioned below when wiring to the powersupply terminal block.- 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 clamping wiring, use the clamps (delivered with theunit) to prevent outside pressure being exerted on the wiringconnections. Tie up firmly. When doing the wiring, make surethe wiring is neat and does not cause the control box to stickup. Close the cover firmly.- 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 block 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 wiring and unit transmission wiring should belocated 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 block fortransmission wiring. This mistake could damage the entire system.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 servicecover. Make sure the cover closes tight. Incomplete connectionscould result in overheating, and in the worse case, electric shockor fire.WIRING EXAMPLEFit the power supply wiring of each unit with a switch and fuse asshown in figure 14.Tightening torque (N•m)Terminal block for unit transmission andremote controller 0.79~0.97Terminal block for power supply 1.18~1.441 2 31 Round crimp-style terminal2 Attach insulation sleeve3 WiringNOTE The customer has the ability to select the remotecontroller thermistor.1 Power supply2 Main switch3 Power supply wiring4 Unit transmission wiring5 Switch6 Fuse7 Indoor unit8 Remote controller
