10.5Digital Ground to Chassis Ground Connectivity

In the default grounding for the MPCBL0001xxx, digital ground is isolated from the chassis ground.

To connect the digital ground to the chassis ground, follow this procedure:

1.Remove the screw with the black insulation washer (circled in red in Figure 28 below).

2.Remove the black insulation washer and store it in a safe place. It will be needed if you want to isolate the digital ground from chassis ground in the future.

3.Reinstall the screw and tighten to 4 lb-in.

Note: Digital ground is also called logic ground. Chassis ground is also known as shelf ground.
