Disturbance from grounding system confusion

Grounding is one of the effective means to improve the electromagnetic compatibility(EMC)of electronic equipment.Correct grounding can not only restrain the influence of electromagnetic interference,but also restrain the equipment from emitting external interference;but wrong grounding will introduce serious interference signals,which will make the PLC system unable to work normally.

来自接地系统混乱时的干扰

接地是提高电子设备电磁兼容性（EMC）的有效手段之一。正确的接地，既能抑制电磁干扰的影响，又能抑制设备向外发出干扰；而错误的接地，反而会引入严重的干扰信号，使PLC系统将无法正常工作。
