Installing the NPE-G1 or NPE-G2

Note The ground lead for the Cisco uBR7200 series DC-input power supply consists of a two-hole grounding

lug that connects to an M5 grounding receptacle; you do not need to strip this ground lead.

Step 4 Connect the two-hole grounding lug on the grounding lead to the M5 grounding receptacles with the M5

nuts. Tighten the nuts using an 8-mm wrench or nut driver (or adjustable wrench). (See Figure 7-30.)

Step 5 Insert the stripped end of the +V lead all the way into the +V lead receptacle and tighten the receptacle

screw using the 3/16-inch flat-blade screwdriver. Repeat this step for the –V lead.

Note Make sure that the entire stripped end of each lead is inserted all the way into its receptacle. If any

exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove

the lead from the receptacle, use the wire stripper to cut the stripped end of the lead, and repeat through

Step 5.

Step 6 After tightening the receptacle screw or nuts for the ground, +V, and –V DC-input leads, secure the leads

to the power supply faceplate.
