ground), is protected by fuses, physically remove the fuses

Installing DC
Power Cables
Plant bus bars may carry 52 volts dc. Observe DANGER
warnings in Section 4.
Use Figures 5-1, 5-3, and 5-4 as references for this section.
1. Turn DC OUTPUT circuit breaker on rectifier Off
(down).
2. Measure the lengths of cable required to run the dc output
from the rectifier to its termination point on the charge bus,
and to run the dc return from the rectifier to its termination
point on the charge ground bus.
3. Cut cables to length and install crimp connectors. Use the
proper crimping tool and die for the connector to prevent
damage to equipment. See Table 5-B.
4. Tape or otherwise insulate the connectors on the end of
each cable that does not terminate in the rectifier.
5. Place dc return cable in cable rack.
6. Thread end of cable through right side of rectifier and
terminate connector at the appropriate ground bus bar in
the rectifier. The ground bus bar is positive for negative
output voltage plants, and negative for positive output
voltage plants. Torque connection to 120 in-lb. See Figure
5-4.
7. Remove tape or insulation from connector at other end of
cable and terminate on plant charge ground bus bar.
8. Place dc output cable in cable rack.
9. Thread end of output cable through right side of rectifier
and terminate connector on CBA1 circuit breaker in
rectifier. Torque to 260 in-lb. See Figure 5-4.
10. Remove tape or insulation from connector at other end of
output cable, and terminate connector on (hot) charge bus
bar.
