Ground and Shield Considerations

Proper grounding is necessary for operator safety, noise reduction, and the protection of equipment from voltage transients. Buildings, including any steelwork, all circuits, and all junction boxes must be grounded directly to an earth ground in compliance with local and national electrical codes.

Ground Loops

Ground loops (signal degradation due to different ground potentials in communicating devices) can be eliminated or minimized by ensuring that both the host, imager, and their power supplies are connected to a common earth ground.

Expected Power and Ground Connections for Proper Operation

Notes:

• Ensure that mounting bracket "Earth" is at the same potential as power source "Earth".

• Supply "Return" and "Earth" ground must be stable, low-impedance reference points.

• "2-Terminal Power Supply" must still provide an "Earth" connection to the imager.

• "Signal Ground" can be used for communications and/or discrete signal ground reference. It must not be used as Power Ground or Earth Ground.
