信号控制电缆采用能耐交流额定电压500伏以上的铜芯电缆。
Signal control cable applied the copper cored cable which may withstand 500 AC rated voltage.
在额定控制电源电压低于35%时，欠电压脱扣器应防止断路器合闸。
At rated control supply voltage less than 35% under-voltage should prevent breaker from closing.
电源电压应控制在不大于或小于额定电压的5%范围内，如果电压过高或过低都会损坏电机。
Supply voltage should be controlled at not more than or less than 5% of rated voltage range, if the voltage too high or too low will damage motor.
