DC-Powered Systems

In a router to be equipped with DC-input power supplies, observe the following guidelines:

•Each DC-input power supply requires a dedicated 40A service.

•For DC power cables, it is recommended that you use 4 AWG, high-strand-count wire cable with dual hole lugs that fit over M6 (metric) terminals centered 0.625 inch (15.86 mm) apart.

For a listing of the electrical specifications for the DC-input power supply, see Table 1-10 in Chapter 1.

Figure 2-6 shows the specifications of the lug used for source DC power cable connections.

Note To prevent the crimp area on the lug (see Figure 2-6) from coming in contact with the metal faceplate of the DC-input power supply, add a length of heat-shrink tubing to this area of the lug to provide extra insulation.
