保障高低压电气成套设备的高低压电气控制柜内的设备接地良好，运用短粗接地线衔接到公共接地点或接地母线。衔接到变频器的控制设备之一应与其接地 ，接地也应运用短而粗的导线。
Ensure that the equipment in the high-voltage and low-voltage electrical control cabinet of high-voltage and low-voltage electrical complete equipment is well grounded, and use short and thick grounding wires to connect to the public grounding point or grounding bus. One of the control equipment connected to the frequency converter shall be grounded, and the grounding shall also use short and thick conductor.
2.高低压电气控制柜里面的低压单元和继电器以及触摸器，其实这些都是由熔断器来进行维护的。那么当变频器和电机之间的衔接超过100m、变频器的电源容量也大于600kw/a、电源的容量也大于变频器的十倍的时分，建议能够加进输入和输出的电抗器。
2. In fact, the low-voltage units, relays and touch devices in the high and low-voltage electrical control cabinet are maintained by fuses. Then, when the connection between the frequency converter and the motor exceeds 100m, the power capacity of the frequency converter is also greater than 600kW / A, and the power capacity is also greater than ten times that of the frequency converter, it is recommended to add the input and output reactors.
3.保障高低压电气控制柜中的触摸器具有灭弧功用。沟通触摸器采用r-c抑制器，直流触摸器采用装置在绕组中的“飞轮”二极管。采用压敏电阻抑制器也是很有效的。
3. Ensure that the touch device in the high and low voltage electrical control cabinet has arc extinguishing function. The communication touch device adopts R-C suppressor, and the DC touch device adopts "flywheel" diode installed in the winding. The use of varistor suppressors is also very effective.
4.设备的工作环境如果是在噪音中，那么就能够运用电磁兼容滤波来进行削减辐射的搅扰。如果想要达到此较好的作用，就需要确认过滤器和装置板之间的触摸是不是正常的。
4. If the working environment of the equipment is in noise, electromagnetic compatibility filtering can be used to reduce the disturbance of radiation. If you want to achieve this better effect, you need to confirm whether the touch between the filter and the device board is normal.
5.电机电缆应与其他控制电缆分开布线，间隔为500毫米。一起应防止电机电缆和控制电缆的长间隔平行布线。如果控制电缆和电源电缆穿插，应尽可能成90角穿插。
5. Motor cables shall be routed separately from other control cables at an interval of 500 mm. Long interval parallel wiring of motor cables and control cables shall be prevented together. If the control cable and power cable are interspersed, they shall be interspersed at a 90 angle as far as possible.
