The motor-compressor shall be connected to a circuit of rated voltage and operated for 1 hour or until stable conditions have been attained, whichever is longer. The applied voltage then is to be reduced to 90 per cent of its rated voltage (if the motor-compressor will operate at that voltage ) and operation continued until stable conditions exist.The applied voltage then is to be reduced in steps of 2 per cent of rated voltage (to the nearest integral volt).Operation shall be allowed to become stable after each reduction in voltage before the next reduction.This procedure shall be continued until the protective device opens the circuit. If the motor-compressor protective device trips at 90 per cent of rated voltage,the voltage applied to the until shall be increased to the rated voltage and the unit operated until stable operation is obtained.The voltage then shall be reduced in the 2 per cent step described above until the protective device opens. The motor-compressor current input a

电机压缩机应连接到电路的额定电压和操作1小时或直至稳定的条件已经实现，两者是更长的时间。

外加电压则降低到百分之九十的额定电压（如电机压缩机将在电压）和运作，一直持续到稳定的条件exist.The然后施加电压要减少步骤百分之二额定电压（至最接近的积分伏） 。

运作应允许趋于稳定后，每减少电压在未来reduction.This程序应持续到保护装置打开电路。

如果电机压缩机保护装置旅行，百分之九十额定电压，电压适用于之前应增加的额定电压和经营单位，直至稳定运行得到的电压是那么应减少在百分之二上述步骤直到保护装置打开。

电机压缩机电流输入的最低电压一步在这期间发生的连续运转（最低电压的电压前在打开的保护电路）须确定。
