A two-hole grounding lug is provided on the left rear of the chassis to connect the
device to earth ground (see Figure 13 on page 20).
To ground the device before connecting power, you connect a grounding cable to
earth ground and then attach the cable to the lug on the rear of the chassis. For
more information, see "Chassis Grounding" on page 26.
