对PLC 本身应按规定的接线标准和接地条件进行接地，而且应注意避免和变频器使用共同的接地线，且在接地时使二者尽可能分开。当电源电压波动大，谐波成分多时，为抑制谐波干扰，应在PLC 的电源模块及输入/ 输出模块的电源线上接入噪音滤波器或者隔离变压器。如果干扰仍严重，应考虑在变频器主回路中接入电抗器、变压器和噪音滤波器等措施。变频器和P L C 安装在同一电控柜时，应尽可能使与变频器有关的电缆和与PLC 有关的电缆分开安装，尤其是连接变频器的强电电缆与连接PLC 的弱电电缆更要分开安装。

The PLC itself should be grounded according to the specified wiring standards and grounding conditions, and attention should be paid to avoiding using a common grounding wire with the frequency converter, and the two should be separated as much as possible during grounding. When the power supply voltage fluctuates greatly and there are many harmonic components, in order to suppress harmonic interference, noise filters or isolation transformers should be connected to the power lines of the PLC power module and input/output module. If the interference is still severe, measures such as adding reactors, transformers, and noise filters to the main circuit of the frequency converter should be considered. When the frequency converter and PLC are installed in the same electrical control cabinet, cables related to the frequency converter and PLC should be installed separately as much as possible, especially the strong current cables connecting the frequency converter and the weak current cables connecting the PLC should be installed separately.
