Grounding
The chassis will not function correctly if it is not grounded as shown. Be sure
your power source is also properly grounded. The chassis includes two grounds:
a chassis ground and a signal ground. The two grounding lugs are connected
together with an external shorting bar when the chassis is manufactured.
•
For the console configuration, remove the shorting bar from the ground lugs
and connect the chassis ground to the console rail.
•
For a stand-alone configuration, always connect the shorting wire to both
ground lugs.
AC grounding
The AC power ground is through the power cord. The power cord must be
plugged into both the chassis and the power source for proper grounding.
