4-1c) GROUNDING
THE POWER SUPPLY CABINET MUST BE GROUNDED AT ALL TIMES!!! ground is totally. Grounding is accomplished by
plugging the power supply into a grounded three prong AC outlet. The power supply‘s electronic floating in respect to the cabinet‘s chassis ground (AC
ground), therefore there is no advantage to removing the third prong on the AC power cord to try to alleviate a ground loop. If the AC ground is defeated
on the power cord or AC outlet then the power supply cabinet MUST be grounded through other means. Failure to do so will result in a safety hazard.
