3. Locate the C GND (chassis ground) studs at the rear of the panel as shown in 

Figure 15

Figure 15. Chassis Ground Connections

4. Connect the ring terminal end of each wire to one of the studs and secure using the nuts

with captive star washers provided (requires 3/8-inch socket). Tighten each stud nut to 23
pound-force inches (2.6 Newton meters) of torque. 

5. Route the free end of each chassis grounding wire to an approved office ground source. 

6. Cut each chassis grounding wire to length and connect it to the office ground source as

required by local code or practice.
