English1-13ELECTRICAL WIRING CONNECTIONIMPORTANT : * The figures shown in the table are for information purpose only. They should be checked and selectedto comply with the local/national codes of regulations. This is also subject to the type of installation andconductors used.** The appropriate voltage range should be checked with label data on the unit.All wires must be firmly connected.Make sure all the wire do not touch the refrigerant pipings, compressor or any moving parts.Make sure no external pressure is applied to the terminal connectors and wires.Make sure all the covers are properly fixed to avoid any gap.Use round crimp-style terminal for connecting wires to the power supply terminal block. Connect the wires by matchingto the indication on terminal block. (Refer to the wiring diagram attached on the unit).•••••Use the correct screwdriver for terminal screws tightening. Unsuitable screwdrivers can damage the screw head.Over tightening can damage the terminal screws.Do not connect wire of different gauge to same terminal.Keep wiring in an orderly manner. Prevent the wiring from obstructing other parts and the terminal box cover.••••Attach insulation sleeveRound crimp-style terminal Electric wireConnect wires of thesame gauge to both side.Do not connect wires of thesame gauge to one side.Do not connect wiresof different gauges.!
