For relay rack / equipment cabinet frame grounding requirements, refer to the current edition of the American National Standards
Institute (ANSI) approved National Fire Protection Association's (NFPA) National Electrical Code (NEC), applicable local codes, and

each relay rack for installing a lead with a two-hole lug that has 1/4" bolt clearance holes on 5/8" centers. When using 1/4-inch
hardware, recommended torque is 84 in-lbs. when a standard flat washer and lock washer are used. Refer to Figure 5.1 for locations.
NOTE!
REMOVE TAPE FROM HOLE LOCATIONS BEFORE INSTALLING LUG.
