A-2-4 Grounding 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.
