ABB 83SR50C-E GJR2395500R1210如果面板有接地螺柱，则使用螺母和星形锁紧垫圈固定接地螺螺柱上的每根电线，以确保充分接地。在与涂漆面板进行连接的情况下，应清除油漆，使连接点处露出裸露的金属。所使用的端子和硬件应与铝背板材料配合使用。ABB 83SR50C-E GJR2395500R1210

所有背板必须接地，ABB 83SR50C-E GJR2395500R1210以最大限度地减少触电危险。否则可能导致严重的人身伤害。

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。

电源接地请参阅本章后面关于电源现场接线的信息。编程器接地为了正确操作，运行PLC软件的计算机（编程器）必须与CPU共用接地连接。ABB 83SR50C-E GJR2395500R1210

ABB 83SR50C-E GJR2395500R1210, if the panel has a ground stud, use a nut and star lock washer for each wire on the ground stud to ensure adequate grounding. Where connections are made to a painted panel, the paint should be removed so clean, bare metal is exposed at the connection point. Terminals and hardware used should be rated to work with the aluminum backplane material.

ABB 83SR50C-E GJR2395500R1210All backplanes must be grounded to minimize electrical shock hazard. Failure to do so can result in severe personal injury.ABB 83SR50C-E GJR2395500R1210

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.

Power Supply Grounding See the information on Power SupplyABB 83SR50C-E GJR2395500R1210 Field Wiring later in this chapter. Programmer Grounding For proper operation, the computer (programmer) running the PLC software must have a ground connection in common with the CPU.ABB 83SR50C-E GJR2395500R1210
