妙文翻译公司翻译样稿n 凡涉及本产品安装、操作、维护的人员必须经过专门的技术培训，并具有高压设备的相关资质，同时应认真阅读本说明书的各项条款n 输入电压应保证在额定范围内n 使用环境应满足产品技术条件n 上电、下电顺序应遵循：上电时应先上控制电，再上高压电断电时应先停机，再断高压电，最后切断控制电源n 产品应根据维护说明进行定期清理维护n 应确保用户接地网的接地电阻小于4欧姆，并采用符合国家标准的接地排、接地线同时应定期对柜内接地电阻（产品出厂检验值：小于100毫欧）及用户系统接地电阻进行测量检查，确保可靠接地n 接触、储存或运送印刷线路板、IGBT模块时应做好静电防护，如戴静电防护手套，使用防静电包装n 当电动机的额定容量小于变频器的额定容量时，应根据电动机的额定参数，调整变频器的过载保护值，以保证电动机安全运行n 应正确使用变频器参数设置中的跳频功能，避开机械负载的固有共振点 n 变频器输出端无需功率因数补偿用电容及浪涌抑制器，原已安装的务请拆除，以免引起保护误动作或设备损坏n 虽然变频器内部设有避雷保护装置，仍请用户自行设置外部避雷网与避雷设施n Any personnel involved in the installation, operation and maintenance of this product must accept specialized technical training and have relevant qualification on high-voltage equipment, and should carefully read provisions of this manual at the same time.n Ensure that input voltage is within the rated range.n The service environment should meet technical requirements of the product.n The power-on and power-off sequences shall be as follows: when powering on, supply the control power first and then the high voltage power; when powering off, stop the equipment first, then cut off high-voltage power, and cut off the control power at last.n The product should be cleaned and maintained regularly in accordance with the maintenance instructions.n Ensure that the grounding resistance of the user earth mats is less than 4 ohms, and that the grounding bars and earth wires up to national standards are used. And regularly measure and check the grounding resistance within cabinet (product factory test value: less than 100 milliohms), and the user's system grounding resistance to ensure a reliable grounding.n When contacting, storing or transporting printed circuit boards, IGBT modules, electrostatic protection measures such as wearing anti-static gloves, the use of anti-static packaging etc. should be taken.n When the rated capacity of the motor is less than the rated capacity of the inverter, adjust the overload protection value of the inverter based on the rated parameters of the motor to ensure safe operation of the motor.n Make proper use of frequency hopping function in the inverter parameter settings, so as to avoid the inherent resonance point of mechanical load.n Power factor compensation capacitors and surge suppressors are not required at the inverter outputs, and if already installed, they should be removed so as to avoid protection misoperation or damage to equipment.n Although there are lightning protection devices inside the converter, the user is still required to establish their own external lightning conduction and lightning protection facilities.妙文上海翻译公司版权所有。
