Installing the Power Components
• Crimping tool and lug specific die
• 3/8-inch drive torque wrench rated to include 30 in-lb (3.39 N-m)
To ensure a satisfactory ground connection:
• One 180-degree angle (straight) grounding lug that has two M6 bolt holes with 0.63 inch (16 mm)
spacing center to center between them, and a wire receptacle able to accept a 2-6-AWG multistrand
copper wire.
• Two M6 bolts with integrated square cone locking washers (shipped pre-installed on the FCC, two at
each grounding point).
• 2-6-AWG multistrand copper ground cable. This cable is not available from Cisco; it is available from
any commercial cable vendor such as Panduit (see http://www.panduit.com). The cable should be sized
according to local and national installation requirements.
Note The DC return of this system should remain isolated from the system frame and FCC (DC-I: Isolated DC
Return).
