ABB 83SR03K-E GJR2342800R1500如果交流或輸出線束必須經(jīng)過噪聲敏感信號線束附近，避免將其并排運行。如果必須交叉，則將它們布置成直角，以最大限度地減少它們之間的耦合。
ABB 83SR03K-E GJR2342800R1500將模塊分組以保持導(dǎo)線隔離如果可行，在背板上將類似的模塊分組在一起可以幫助保持導(dǎo)線隔離。ABB 83SR03K-E GJR2342800R1500例如，一個背板可以只包含AC模塊，而另一個背板只能包含DC模塊，并按輸入和輸出類型進(jìn)一步分組。
ABB 83SR03K-E GJR2342800R1500系統(tǒng)接地控制系統(tǒng)的所有組件及其控制的設(shè)備必須正確接地。這一點尤為重要，原因如下。? 在短路或設(shè)備故障的情況下，從系統(tǒng)所有部件到接地的低電阻路徑可最大限度地減少電擊。
? ABB 83SR03K-E GJR2342800R1500系統(tǒng)需要正確接地才能正常工作。? PLC系統(tǒng)中組合在一起的所有背板必須具有公共接地連接。這對于不安裝在同一控制柜中的背板尤為重要。ABB 83SR03K-E GJR2342800R1500
英文資料：
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.
