Raise the rated voltage or utility special transformer.

选择高电压等级或者利用专用变压器供电；

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。

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。

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。

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。
