179. WIRING EXAMPLE AND HOW TO SETTHE REMOTE CONTROLLER9-1 HOW TO CONNECT WIRINGS• Lower the electric parts box, as shown in the drawing, tomake connections.NOTE• After wiring, adhere the sealing material (1 3/8” × 5 7/8”)around the wires as shown below.[Be sure to adhere it to avoid water from outside unit.]CAUTION• Be sure to attach the sealing material or putty (field supplied)to hole of wiring to prevent the infiltration of water as well asany insects and other small creatures from outside. Other-wise a short-circuit may occur inside the electric parts box.• When clamping the wires, be sure no pressure is applied tothe wire connections by using the included clamping materialto make appropriate clamps. Also, when wiring, make surethe lid on the electric parts box fits snugly by arranging thewires neatly and attaching the electric parts box lid firmly.When attaching the electric parts box lid, make sure no wiresget caught in the edges. Pass wiring through the wiringthrough holes to prevent damage to them.• Make sure the remote controller wiring, the wiring betweenthe units, and other electrical wiring do not pass through thesame locations outside of the unit, separating them by atleast 1 15/16”, otherwise electrical noise (external static)could cause mistaken operation or breakage.NOTE1. Use round crimp-style terminals for connecting wires to thepower supply terminal block.If unavailable, observe the following points when wiring.• Do not connect wires of different gauge to the samepower supply terminal.(Looseness in the connection may cause overheating.)• Use the specified electric wire. Connect the wire securelyto the terminal. Lock the wire down without applyingexcessive force to the terminal. (Tightening torque:0.97ft.lbf ±10 %)2. Tightening torque for the terminal screws.• Use the correct screwdriver for tightening the terminalscrews. If the blade of screwdriver is too small, the headof the screw might be damaged, and the screw will not beproperly tightened.• If the terminal screws are tightened too hard, screwsmight be damaged.• Refer to the table below for the tightening torque of theterminal screws.3. Do not connect wires of different gauge to the samegrounding terminal. Looseness in the connection may dete-riorate protection.4. Outside of the unit, keep transmission wiring at least1 15/16” away from power supply wiring. The equipmentmay malfunction if subjected to electrical (external) noise.5. For remote controller wiring, refer to the “INSTALLATIONMANUAL OF REMOTE CONTROLLER” attached to theremote controller.6. Never connect power supply wiring to the terminalblock for remote controller wiring. A mistake of the sortcould damage the entire system.7. Use only specified wire and tightly connect wires to termi-nals. Be careful wires do not place external stress on termi-nals. Keep wiring in neat order and so as not to obstructother equipment such as popping open the electric partsbox lid. Make sure the lid closes tight. Incomplete connec-tions could result in overheating, and in worse case, electricshock or fire.Terminal Size Tightening torque(ft.lbf)Terminal block for remote controller (6P) M3.5 0.58 – 0.72Power supply terminal block M4 0.87 – 1.06Ground terminal M4 1.06 – 1.43
