Cabling Instr uctions for the –48 VDC
1-3
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.
