1·Not be more than the rated voltage of the system by 1.5 times.

系统的工作电压应不大于系统额定电压的1.5倍。

2·Auxiliary contactors contact rated voltage of 380v ac, DC to 220v.

接触器辅助触头额定电压为交流380v，直流为220v。

3·Rated voltage lines higher insulation to the longer ionization time.

线路额定电压越高，绝缘去电离时间越长。

4·The maximum wattage and rated voltage are shown on the heater data plate.

在热水器的规格面板上，标注着最大功率瓦数和额定电压。

5·The average of the line currents at rated voltage is the no-load current.

额定电压下线路电流的平均值即是空载电流。

6·The peak value of the ripple voltage should be less than the rated voltage.

所施加纹波电压的峰值应小于额定工作电压。

7·The voltage should stable and amplitude should not over 15% of rated voltage.

电源电压应保持稳定，其波动值不超过额定电压的15％。

8·Before switching on, make sure that supply voltage is consistent with rated voltage.

打开电源前确保供电电源电压与额定电压相符。

9·Compliance is checked by measurement, the appliance being supplied at rated voltage.

通过对由额定电压供电的器具的测量确定其是否合格。

10·The symbol for nature of supply shall be placed next to the marking for rated voltage.

电源性质的符号，应紧靠所标示的额定电压值。
