CD 30 ÷ 520Earthing wire22——High speed of outdoor fan, controlled by T4.23——Low speed of outdoor fan, controlled by T4.24——PWM, used for digital compressor capacity adjustment. (Just valid for main unit).25——Transformer input, 220V/AC.26——Power input by three-phase four-wire system (E1 for failure code).A, B, C phases should be supplied together with the 120 degree angle difference amongthree phases. If it is not qualified, it may cause phases sequence failure or phases absentfailure then the corresponding code will be displayed until the power get right. Notice:phases sequence failure or phases absent failure are just checked at the beginning ofelectrifying. During the running, they will not be detected.27——Transformer output50
