加濕器的電氣連接一定需要專業(yè)人員操作嗎？
The electrical connection of the humidifier needs to be carried out by qualified professionals.
機組使用的電源應(yīng)由專線提供作業(yè)，機組提供了完整的內(nèi)部電路，電路的安裝及配置均按照設(shè)備銘牌中所標(biāo)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(jìn)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(jìn)線為五色電纜，接入機組電器柜的相應(yīng)接線端子排上；在連接機組總電源進(jìn)線時，需要注意五色電纜中線直徑較細(xì)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(yīng)對三相交流供電進(jìn)行檢查，以確保所供電壓波動范圍不超過設(shè)備表明電壓及頻率的10%，對于高負(fù)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(shè)置帶熔斷器的空氣開關(guān)以保證設(shè)備在檢查和服務(wù)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(yīng)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(yīng)正確的尺寸及熔斷功率，細(xì)節(jié)參見附后的電氣資料；機組的電源進(jìn)線上需要增加火警斷電保護(hù)以便及時發(fā)現(xiàn)問題、減少不必要的麻煩。
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.
