ABB 83SR50C-E GJR2395500R1210如果面板有接地螺柱，則使用螺母和星形鎖緊墊圈固定接地螺螺柱上的每根電線，以確保充分接地。在與涂漆面板進(jìn)行連接的情況下，應(yīng)清除油漆，使連接點(diǎn)處露出裸露的金屬。所使用的端子和硬件應(yīng)與鋁背板材料配合使用。ABB 83SR50C-E GJR2395500R1210

所有背板必須接地，ABB 83SR50C-E GJR2395500R1210以最大限度地減少觸電危險(xiǎn)。否則可能導(dǎo)致嚴(yán)重的人身傷害。

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(duì)于不安裝在同一控制柜中的背板尤為重要。

電源接地請(qǐng)參閱本章后面關(guān)于電源現(xiàn)場(chǎng)接線的信息。編程器接地為了正確操作，運(yùn)行PLC軟件的計(jì)算機(jī)（編程器）必須與CPU共用接地連接。ABB 83SR50C-E GJR2395500R1210

英文資料：

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
