Precautions on wiring of power supply and inter-unit wiring Use a round crimp-style terminal for connection to the powersupply terminal board. In case it cannot be used due tounavoidable reasons, be sure to observe the followinginstruction.- 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 below figure. Use the correct screwdriver to tighten the terminal screws.Small screwdrivers can damage the screw head and preventappropriate tightening. Over-tightening the terminal screws can damage the screws. See the table below for tightening torques for the terminalscrews. Refer to the installation manual attached to the indoor unit forwiring of indoor units, etc. Attach an earth leakage breaker and fuse to the power supplyline.
