DC Supplies
The DC power supplies have additional ground connections on each supply. This
allows the hot-swappable supply to be connected to power, return and ground so
that it may be safely inserted. This ground lug must be attached.
It is a M4 screw with an outside-toothed lock washer screw.
The ground wire should be sized to match the breaker for the circuit.
