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 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—起工作。所有基板必须接地，以将电击危险降至zui低。

The GE WHEDCO 78004654 Power module uses machine screws, star lock washers and flat washers to connect the other end of the ground cable to the threaded hole on the panel where the substrate is installed. Alternatively, if your panel has ground studs, it is recommended that you use nuts and star lock washers for each wire on the ground to ensure adequate grounding.

When connecting to a painted panel, the paint should be removed so that it is clean and bare metal is exposed at the connection point. The terminals and hardware used shall be rated to work with aluminum substrate materials. All substrates must be grounded to minimize the risk of electric shock.

GE WHEDCO 78004654 Power module Otherwise, serious injury may occur. All substrates assembled together in a Series 90-30 PLC system must have a common ground connection. This is especially important for baseboards that are not installed in the same control cabinet. Ground 19 "rack mount substrate There are two adapter brackets for mounting the 10-slot Series 90-30 substrate to the 19" rack. Regardless of which adapter bracket is used, the 19 "rack should be grounded according to the instructions in the" System Grounding Procedure "(including Figure 2-10).
