Step 5 Using an 8-mm wrench or nut driver (or adjustable wrench), loosen and remove the two M5 nuts that
secure the two-hole grounding lug to the grounding receptacle, and pull the grounding lug and lead from
the receptacle.
Note The color coding of the DC-input power supply leads depends on the color coding of the DC
power source at your site. Typically, green or green and yellow are used for ground. Make certain
that the lead color coding you choose for the DC-input power supply matches the lead color
coding used at the DC power source.
