ABB 83SR03K-E GJR2342800R1500如果交流或输出线束必须经过噪声敏感信号线束附近，避免将其并排运行。如果必须交叉，则将它们布置成直角，以最大限度地减少它们之间的耦合。
ABB 83SR03K-E GJR2342800R1500将模块分组以保持导线隔离如果可行，在背板上将类似的模块分组在一起可以帮助保持导线隔离。ABB 83SR03K-E GJR2342800R1500例如，一个背板可以只包含AC模块，而另一个背板只能包含DC模块，并按输入和输出类型进一步分组。
ABB 83SR03K-E GJR2342800R1500系统接地控制系统的所有组件及其控制的设备必须正确接地。这一点尤为重要，原因如下。▪ 在短路或设备故障的情况下，从系统所有部件到接地的低电阻路径可最大限度地减少电击。
▪ ABB 83SR03K-E GJR2342800R1500系统需要正确接地才能正常工作。▪ PLC系统中组合在一起的所有背板必须具有公共接地连接。这对于不安装在同一控制柜中的背板尤为重要。ABB 83SR03K-E GJR2342800R1500

Where AC or Output wiring bundles must pass near noise-sensitive signal wiring bundles, avoid running them beside each other. If they have to crossABB 83SR03K-E GJR2342800R1500, route them a right angle to minimize coupling between them.ABB 83SR03K-E GJR2342800R1500
Grouping Modules to Keep Wires Segregated If practical, grouping similar modules together on the backplanes can help keep wiring segregated. For example, one backplane could contain only AC modules, and another only DC modules, ABB 83SR03K-E GJR2342800R1500with further grouping by input and output types.
System Grounding All components of a control system and the devices it is controlling must be properly grounded. This is particularly important for the reasons listed below. ▪ A low resistance path from all parts of a system to earth minimizes exposure to shock in the event of short circuits or equipment malfunction.ABB 83SR03K-E GJR2342800R1500
▪ The ABB 83SR03K-E GJR2342800R1500 system requires proper grounding for correct operation. ▪ All backplanes grouped together in the PLC system must have a common ground connection. This is especially important for backplanes that are not mounted in the same control cabinet.
