加湿器的电气连接需要由具有资格的专业人员执行
The electrical connection of the humidifier needs to be carried out by qualified professionals.
机组使用的电源应由专线提供作业，机组提供了完整的内部电路，电路的安装及配置均按照设备铭牌中所标定的电压及频率；机器不可在超过制造范围的电压及频率下进行操作。
The power supply used by the unit should be provided by a dedicated line. The unit provides a complete internal circuit. The installation and configuration of the circuit are in accordance with the voltage and frequency specified in the equipment nameplate. The machine can not operate beyond the voltage and frequency of the manufacturing range.
机组总电源进线为五色电缆，接入机组电器柜的相应接线端子排上；在连接机组总电源进线时，需要注意五色电缆中线直径较细的芯线接三相电源中线，黄绿线接地，其余三根线接电源。
The main power supply line of the unit is a five-color cable, which is connected to the corresponding terminal row of the electrical cabinet of the unit.
在机组接通主电源前，应对三相交流供电进行检查，以确保所供电压波动范围不超过设备表明电压及频率的10%，对于高负荷场合能够引起电压的波动，此项检查尤为重要；机组必须接地，且设置带熔断器的空气开关以保证设备在检查和服务时与电源绝缘。
Before the unit is connected to the main power supply, the three-phase AC power supply should be checked to ensure that the range of voltage fluctuation does not exceed 10% of the indicated voltage and frequency of the equipment. It is insulated from the power supply during inspection and service.
熔断器的熔断功率必须与所安装机组的型号及类型相一致。熔断器应该安装在容易触及的机组控制板上；电缆尺寸及熔断功率，供电电缆及主电熔器对于所安装的机组来说必须有对应正确的尺寸及熔断功率，细节参见附后的电气资料；机组的电源进线上需要增加火警断电保护以便及时发现问题、减少不必要的麻烦。
The fusing power of fuses must be consistent with the type and type of installed units. The fuse should be installed on the easy-to-touch unit control board; the cable size and fusing power, power supply cable and main fuse must have the correct size and fusing power for the installed unit. See the attached electrical data for details; the power supply line of the unit needs to be protected against fire and power failure in time. Identify problems and reduce unnecessary troubles.
