ABB 87TP01-ER1210通常,這種公共接地連接是通過將編程器的電源線連接到與背板相同的電源(具有相同的接地參考點)來提供的。如果編程器接地電位與PLC接地電位不同,則可能存在電擊危險。此外,當編程器串行電纜連接在兩個端口之間時,可能會損壞端口。
通常,ABB 87TP01-ER1210鋁PLC背板用于模塊屏蔽接地。在某些模塊上,與模塊上用戶終端連接器的屏蔽連接通過模塊的背板連接器路由到背板。其他模塊,如DSM314,需要單獨的屏蔽接地,如本手冊中的模塊說明所示。ABB 87TP01-ER1210
對于安裝在通用背板中的模塊,可以使用尺寸為M3的螺釘將屏蔽接地連接到背板底部的接地棒。建議的扭矩最大為4英寸/磅。ABB 87TP01-ER1210
通用背板使用四個優質8-32 x 1/2(4 x 12mm)機器螺釘、鎖緊墊圈和平墊圈安裝通用背板。將螺釘安裝到四個螺紋孔中。ABB 87TP01-ER1210
英文資料:
Normally, this common ground connection is provided by connecting the programmer’s power cord to the same power source (with the same ground reference point) as the backplane. If the programmer ground is at a different potential than the PLC ground, a shock hazard could exist. Also, damage to the ports could occur when the programmer serial cable is connected between the two.ABB 87TP01-ER1210
In general, the aluminum PLC backplane is used for module shield grounding. On some modules, shield connections to the user terminal connector on the module are routed to the backplane through the module’s backplane connector. Other modules, such as the DSM314 require a separate shield ground, as shown in the module descriptions in this manual.ABB 87TP01-ER1210
For modules installed in a Universal Backplane, shield grounds can be connected to the Grounding Bar at the bottom of the Backplane using size M3 screws. The recommended torque is 4 in/lb maximum.
Universal Backplanes Mount a Universal Backplane using four good-quality 8-32 x 1/2 (4 x 12mm) machine screws, lock washers and flat washers. Install the screws in the four tapped holes.
