加濕器的電氣連接一定需要專業(yè)人員操作嗎

？

，機組提供了完整的內部電路，電路的安裝及配置均按照設備銘牌中所標定的電壓及頻率；機器不可在超過制造范圍的電壓及頻率下進行操作。
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.
機組總電源進線為五色電纜，接入機組電器柜的相應接線端子排上；在連接機組總電源進線時，需要注意五色電纜中線直徑較細的芯線接三相電源中線，黃綠線接地，其余三根線接電源。
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.
在機組接通主電源前，應對三相交流供電進行檢查，以確保所供電壓波動范圍不超過設備表明電壓及頻率的10%，對于高負荷場合能夠引起電壓的波動，此項檢查尤為重要；機組必須接地，且設置帶熔斷器的空氣開關以保證設備在檢查和服務時與電源絕緣。
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.
熔斷器的熔斷功率必須與所安裝機組的型號及類型相一致。熔斷器應該安裝在容易觸及的機組控制板上；電纜尺寸及熔斷功率，供電電纜及主電熔器對于所安裝的機組來說必須有對應正確的尺寸及熔斷功率
