Dell PowerEdge 2650 Cabling Instructions for the –48 VDC - Page 5

To construct the DC input power cable, perform the following steps: 1 Strip the insulation from the ends of the six DC power wires, exposing approximately 4.5 mm (0.175 inches) of copper wire. 2 Using a hand-crimping tool, crimp a connector contact to each DC power wire. 3 Slide a piece of heat-shrink tubing over the DC power cable. The heat-shrink tubing should be approximately 3.175 cm (1.25 inches) in length. 4 Insert the three black -48 VDC wires into connector housing positions 2, 3, and 6 (see Figure 1-1 and Table 1-1). 5 Insert the three red -48 VDC return wires into connector housing positions 1, 4, and 5 (see Figure 1-1 and Table 1-1). 6 Slide the heat-shrink tubing over the DC power cable so that it overlaps the connector housing by at least 6.35 mm (0.25 inches). 7 Using a heat gun, shrink the tubing around the cable and connector housing.
