关于配线
About the wiring
为了避免在运用方面出现因上位系统接地短路继电器等的动作导致电源系统全体停止，而未安装与电源系统相
In order to avoid the use of grounding system, short circuit relay and other actions, the power system is stopped, and the power supply system is not installed.
适应的漏电（零相电流）检测设备时，请单独安装漏电断路器(ELCB)，以便仅切断变频器的电源系统。
When fitting the leakage current (zero phase current) detection equipment, install the leakage current circuit breaker (ELCB) individually, so as to cut off the power supply system of the inverter only.
・ 请将各变频器通过配线用断路器或漏电断路器（带过电流保护功能）连接至电源。请使用的配线用断路器
Please connect the frequency converters to the power supply through circuit breakers or leakage circuit breakers (with over current protection function). Please use the recommended wiring circuit breaker
和漏电断路器，不得使用功率以上的断路器。
And circuit breaker should not use circuit breaker above recommended power.
・ 请务必使用指定尺寸的电线。
Be sure to use the specified size of wire.
・ 请使用规定的紧固转矩紧固端子。
Please use the prescribed fastening torque to fasten the terminal.
・ 多台变频器和电机组合使用时，请勿使用多芯电缆将多组配线收纳在一起。
When multiple inverters and motors are used together, do not use multi core cable to store multiple wiring.
・ 请勿在变频器的输出侧（二次侧）安装浪涌抑制器。
Do not install surge suppressors on the output side of the frequency converter (the two side).
・ 电源变压器的功率在 500kVA 以上且为变频器额定功率的 10 倍以上时，请务必连接直流电抗器（选配件）。
When the power of the power transformer is above 500kVA and is more than 10 times the rated power of the inverter, please connect the DC reactor.
有可能引起火灾
It is possible to cause a fire
・ 按照国际或当地电气规范将变频器接地。
In accordance with international or local electrical specifications, frequency converter will be grounded.
・ 变频器接地用端子[ G]的接地线请务必接地。
Inverter grounding terminals [G] grounding line must be grounded.
有可能引起触电或火灾
It is possible to cause an electric shock or a fire
・ 由具有资格的专业人员进行配线作业。
* wiring work is performed by qualified professionals.
・ 确认电源切断后再进行配线作业。
Verify that the power supply is cut off and then the wiring operation is carried out.
有可能引起触电
It is possible to cause electric shock
务必在安装主体后再进行配线。
Be sure to do the wiring after the installation of the main body.
有可能引起触电或受伤
It is possible to cause electric shock or injury
请确认产品输入电源的相数、额定电压与连接的电源相数、电压一致。
Please confirm that the number of input power and rated voltage of the product are consistent with the number and voltage of the connected power supply.
请勿在变频器输出端子(U, V, W) 上连接电源线。
Do not connect the power cord on the inverter output terminals (U, V, W).
连接制动电阻器时，请勿连接至 P(+)-DB 以外的端子。
When connecting the brake resistor, do not connect to the terminals other than P (+) -DB.
有可能引起火灾或事故
It is possible to cause a fire or an accident.
通常控制信号线的表层未经过强化绝缘，因此，控制信号线直接接触主电路导电部位时，可能会因某种原因导
Generally, the surface of the control signal line is not strengthened by insulation. Therefore, when the control signal line directly contacts the conductive part of the main circuit, it may lead to some reason.
致绝缘表层破坏。此时，可能会有向控制信号线施加主电路高电压的危险，因此，注意不要使控制信号线接触
Destroy the insulation surface. At this point, there may be danger of applying a high voltage to the main circuit of the control signal line, so be careful not to touch the control signal line.
主电路导电部位。
