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 care should be taken to avoid using a common grounding wire with the frequency converter, and the two should be separated as far as possible when grounded. When the power supply voltage fluctuation is large, in order to suppress harmonic interference, noise filter or isolation transformer should be connected to the power line of the PLC power module and the input/output module.

If the interference is still serious, measures such as reactors, transformers and noise filters should be considered in the main circuit of the inverter. When the frequency converter and the PCB are installed in the same electric control cabinet, the cables related to the frequency converter and the cables related to the PLC should be installed separately as far as possible, especially the strong current cable connecting the frequency converter and the weak current cable connecting the PLC should be installed separately.
