3911.3.4 Connect the Cable to the Indoor Unit1 Connecting cable between indoor unit and outdoor unit shall be approved polychloroprene sheathed (6 x min1.5 mm2) flexible cord, type designation 60245 IEC 57 or heavier cord.o Ensure the colour of wires of outdoor unit and the terminal Nos. are the same to the indoor unit’srespectively.o Earth wire shall be longer than the other wires as shown in the figure for the electrical safety in case ofthe slipping out of the cord from the Holder (Clamper).2 Cable connection to the power supply through isolating device (Disconnecting means).o Isolating device (Disconnecting means) should have minimum 3.0 mm contact gap.o Connect the approved polychloroprene sheathed power supply 1 cord (5 x min 1.5 mm 2) and powersupply 2 cord (3 x min 1.5 mm 2) and power supply 3 cord (5 x min 1.5 mm 2), type designation 60245IEC 57 or heavier cord to the terminal board, and to the other end of the cord to isolating device(Disconnecting means).3 To avoid cable and cord harmed by sharp edge, cable and cord must go through bushing (located at thebottom of indoor unit) before carry out electrical connection. The bushing must be used and must not take off.Connecting with external device (optional)1 All connections shall follow to the local national wiring standard.2 It is strongly recommended to use manufacturer-recommended parts and accessories for installation.3 Maximum output power of booster heater shall be 3 kW. Booster Heater’s cord must be (3 x min 1.5 mm 2),of type designation 60245 IEC 57 or heavier.4 Two-way Valve shall be spring and electronic type, refer to “Field Supply Accessories” table for details.Valve’s cable shall be (3 x min 0.5 mm2), of type designation 60245 IEC 57 or heavier, or similarly doubleinsulation sheathed cable.* note: - Two-way Valve shall be CE marking compliance component.- Maximum load for the valve is 3VA.5 Three-Way Valve shall be spring and electronic type. Valve’s cable shall be (3 x min 0.5 mm 2), of typedesignation 60245 IEC 57 or heavier, or similarly double insulation sheathed cable.* note: - Shall be CE marking compliance component.- It shall be directed to heating mode when it is OFF.- Maximum load for the valve is 3VA.6 Receiver shall be connected to “Room Thermostat”, refer to “Field Supply Accessories” table for details.Receiver’s cable must be (4 or 3 x min 0.5 mm 2), double insulation layer of PVC-sheathed or rubber-sheathed cable. (connection refer to Diagram 5.2).7 Tank OLP’s cable must be (2 x min 0.5 mm 2), double insulation layer of PVC-sheathed or rubber-sheathedcable.* note: if such connection deemed NOT necessary for tank OLP, please connect jumper between terminal no#13 and #14.8 Tank Sensor shall be resistance type, please refer to Graph 5.1 for the characteristic and details of sensor. Itscable shall be (2 x min 0.3 mm2), double insulation layer (with insulation strength of min 30V) of PVC-sheathedor rubber-sheathed cable.9 External Controller shall be connected to 1-pole switch with min 3.0mm contact gap. (connection refer toDiagram 5.3). Its cable must be (2 x min 0.5 mm 2), double insulation layer of PVC-sheathed or rubber-sheathed cable.* note: - When making such connection, kindly remove the jumper between terminal no #17 and #18.- Switch used shall be CE marking compliance component.- Maximum operating current shall be less than 3A rms .10 Solar Three-way Valve’s cable shall be (3 x min 0.5 mm 2), double insulation layer PVC-sheathed or rubber-sheathed cable.11 Must install Solar Connection PCB 0 to indoor unit when Solar Pump Station is utilized. Refer SolarConnection PCB’s installation instruction for detail of installation.
