Installation and wiring

●The power line,control line,and PLC power line and I/O line should be wired separately,and the isolation transformer should be connected with PLC and I/O by double glue line.Separate the IO line and the high-power line of the PLC.If they must be in the same line slot,bundle the AC line and the DC line separately.If conditions permit,it is best to route the line in a separate slot,which can not only make it as large as possible.Spatial distance,and can minimize interference.

●PLC should be far away from strong interference sources such as electric welding machines,high-power silicon rectifiers and large power equipment,and cannot be installed in the same switch cabinet with high-voltage electrical appliances.The PLC in the cabinet should be kept away from the power line(the distance between the two should be greater than 200mm).Inductive loads installed in the same cabinet as PLC,such as relays with higher power and coils of contactors,should be connected in parallel with RC arc suppression circuits.

●The input and output of PLC should be routed separately,and the switch quantity and analog quantity should also be laid separately.Shielded wire should be used for the transmission of analog signals,one or both ends of the shielding layer should be grounded,and the grounding resistance should be less than 1/10 of the resistance of the shielding layer.

●Do not use the same cable for the AC output line and the DC output line.The output lines should be kept away from high-voltage lines and power lines as much as possible to avoid paralleling.

安装与布线

●动力线、控制线以及PLC的电源线和I/O线应分别配线，隔离变压器与PLC和I/O之间应采用双胶线连接。将PLC的IO线和大功率线分开走线，如必须在同一线槽内，分开捆扎交流线、直流线，若条件允许，分槽走线最好，这不仅能使其有尽可能大的空间距离，并能将干扰降到最低限度。

●PLC应远离强干扰源如电焊机、大功率硅整流装置和大型动力设备，不能与高压电器安装在同一个开关柜内。在柜内PLC应远离动力线（二者之间距离应大于200mm）。与PLC装在同一个柜子内的电感性负载，如功率较大的继电器、接触器的线圈，应并联RC消弧电路。

●PLC的输入与输出最好分开走线，开关量与模拟量也要分开敷设。模拟量信号的传送应采用屏蔽线，屏蔽层应一端或两端接地，接地电阻应小于屏蔽层电阻的1/10。

●交流输出线和直流输出线不要用同一根电缆，输出线应尽量远离高压线和动力线，避免并行。
