9、列II特别注意：多台机组时，室外机要求单独供电，也即有几个室外机必须几个室外机电源开关，同一机组的室内机统一供电，不同机组的室内机电源线不能串接。2.1.2电源线的规格★电源线规格基本上根据机型进行选用，选用的电源线必须满足表2・1的要求。★室内机电源连

10、接线主线的最大电流必须满足所有室内机最大电流之和的1・5~2倍。★必须保证供电电源的容量足够大★电源线应有一定的机械强度，电源线材质默认为铜芯，工作温度最高为65°C。表2-1：室外机电源线截血积要求机型电源线（截面X根数）（mm2X根）最大电流（A）机型电源线（截面X根数）（mm2X根）最大电流（A）GMV(L)-R300W226.0X531.5GMV(L)-R120W>6.0X326GMV(L)-R250W236.0X524GMV(L)-R100W>6.0X326GMV(L)-R200W224.0X519GMV(L)-R280P/A$6.
