Chapter 2 System Components Expected Power and Ground Connections for Proper Operation 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. 2-18 Vision HAWK Smart Camera Guide
