GE WHEDCO 78004654电源模块中文资料：
GE WHEDCO 78004654电源模块使用机器螺钉、星形锁紧垫圈和平垫圈将接地线的另一端连接到安装基板的面板上的螺纹孔。或者，如果您的面板有接地螺柱，建议您为接地螺上的每根电线使用螺母和星形锁紧垫圈，以确保充分接地。当连接到涂漆面板时，应清除油漆，使其干净，裸露金属暴露在连接点。所用端子和硬件的额定值应能与铝基板材料一起工作。所有基板必须接地，以将电击危险降至最低。GE WHEDCO 78004654电源模块否则可能导致严重的人身伤害。在Series 90-30 PLC系统中组合在一起的所有基板必须具有公共接地连接。这对于未安装在同一控制柜中的底板尤为重要。接地19“机架安装基板有两个适配器支架用于将10槽Series 90-30基板安装到19”机架上。无论使用哪一个适配器支架，19”机架都应按照“系统接地程序”（包括图2-10）中的说明接地。（有关适配器支架的详细信息，请参阅本章前面的“将底板安装到19英寸机架”一节。）GE WHEDCO 78004654电源模块
英文资料
Connect the other end of this ground wire to a tapped hole in the panel that the baseplate is mounted to, using a machine screw, star lock washer, and flat washer. Alternately, if your panel has a ground stud, it is recommended you 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 baseplate material.All baseplates must be grounded to minimize electrical shock hazard. Failure to do so can result in severe personal injury All baseplates grouped together in a Series 90-30 PLC system must have a common ground connection. This is especially important for baseplates that are not mounted in the same control cabinet. Grounding 19" Rack-Mounted Baseplates There are two Adapter Brackets used for mounting a 10-slot Series 90-30 baseplate to a 19” Rack. Regardless of which of the two Adapter Brackets is used, the 19” Rack should be grounded as per the instructions in “System Grounding Procedures,” including Figure 2-10. (For details on the Adapter Brackets, see the “Mounting a Baseplate to a 19” Rack” section earlier in this chapter.)GE WHEDCO 78004654电源模块
