1.3.4.4 ELECTRICAL GROUNDING
The Standalone, Panelmount OCM enclosure must be electrically connected to earth ground. This
may be accomplished by connecting the Chassis Ground on the Auxiliary Power Supply Pl connec-
tor to earth ground, or by attaching a ground electrode directly to the chassis or module cover.
Figure 12 illustrates how to attach a ground lug to the module cover by using one of the module
mounting bolts. To ensure a good electrical connection between the ground lug and the module,
remove paint from the cover where the lug makes contact. Connect the ground lug to earth ground
with an adequate grounding electrode.
