10CautionThe specifications of the power circuit are listed in the table below. Smaller capacity may causeoverheat or burnout.Power specificationsElectric leak breaker should be installed. Without it, shock accidents may occur.To avoid danger, damaged cable must be replaced by professionals of cable makers or the like. Wiresused by the indoor unit should be selected according to the installation manual.Never connect the block terminal in the control circuit (A, B, C, P, Q, X and Y) to a 220-230V or a380-400V power line. Otherwise, it may lead to mechanical damage or personal injury.Avoid contact of electric wires with high temperature pipes to prevent melting of the outer isolation.Wires should be made into a ì Uî shape after connected to the block terminal, and fixed with clips.Controlling wires may be laid and fixed together with the refrigerant tubes.If the supply cord is damaged,it must be replaced by the manufaturer or its service agent or a similarqualified person.The wiring method should be in line with the local wiring standard.All the cables shall have got the European authentication certificate.The breaker of the air conditioner should be all-pole switch,and the distance between its two contactsshould be no less 3mm.Such means for disconnection must be incorporation in the fixed wiring.The power cable and connecting cable are self-provided.Electrical installation should be entrusted with qualified servicemen and done in accordance with theinstallation manual. Special return circuit must be used. Insufficient capacity return circuit andinappropriate installation may lead to fire accidents.Specific cables should be used for the wiring. To avoid external tension of the cables, the terminalsshould be firmly fixed. Inappropriate connection and fixture may lead to fire accidents.The unit must be earthed.The unit should be earthed properly. Poor earth may lead to shocks. The earth wire should not beconnected to gas pipes, water pipes, lightning rods or telephone wires.Warning1) The type of connecting wire is shielded wire.The type of the power cord is H07RN-F(3G).2) The wiring diagram refer to the wiring diagram on the indoor and outdoor units.NOTE:AB072~282FDAHAAB072~282FDBHAIndoor unitpower15A H05RN-F3G1.5mm25 A /2 5 0VACAC220-230V,50Hz2 500m<1000m2.5mm2L 50mManualswitch2 3< 500m1.5mm2< 500m1.5mm2< 200m0.75mm2200m<500m1mm2ItemModelFuseConnecting cablePower wire (L) Central controllerholding wireIndoor & outdoorcommunication wire Remote controller wireNumber ofcoresCore sec-tional areaNumber ofcoresCore sec-tional areaNumber ofcoresCore sec-tional areaElectrical wiring & Application control11Wiring should be done according to the number of theblock terminal,inappropriate connetction may lead to error.Indoor power wiringThe indoor and outdoor units should use separate special power lines.If several indoor units connect the same outdoor unit, the leak breakers andswitches of the indoor units should use the same power.Centralized controller communication wiringThe centralized controller communication wire arenon-polarity 2-core wires.
