Table 13: DC Power and Grounding Cable Specifications
Both the grounding studs and each pair of terminal studs on the circuit breaker box are
spaced at 0.625-in. (15.86-mm) centers. The accessory box shipped with the router includes
the cable lugs that attach to the end of the power and grounding cables (see Figure 20). The
spacing of the holes in the lug matches the spacing of the terminal grounding studs.

During router installation, secure the grounding cable to the grounding studs and the power
cables to the terminal studs, in that order. Secure the grounding cable lug with washers, then
with 7/16-in. nuts. Then remove the plastic protective shield that covers the power supply
terminal studs as shipped, and secure the power cable lugs to the terminal studs with locking
washers, then with nuts, as shown in Figure 19. Replace the plastic protective shield. The
nuts and washers that secure the power cables to the terminal studs are already installed on
the studs.
