2000 400A, 60Hz Ferroresonant Rectifier J85503C-3
5 - 12 Installation
Issue 10 July 2000
DC Power Cables
Plant bus bars carry 52 volts dc. Observe DANGER warnings in Section
4. Use Figures 5-3 and 5-4 as references for this section.
1. Turn circuit breaker, CB1 on the rectifier, off (down).
2. Measure the lengths of cable required to run the dc output cable
from the rectifier to its termination point on the charge bus, and to
run the dc return cable 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-C.
4. Tape or otherwise insulate the connectors on the end of each cable
that does not terminate in the rectifier. Label each cable.
5. Place the dc output return cable in cable rack.
6. Insert ends of return cables through top of rectifier and terminate
connector on the positive ground bus bar in the rectifier. Torque
connections to 30 Nm (240 in-lb). See Figure 5-3.
7. One at a time, remove tape or insulation from connector at other
end of return cable and terminate on plant charge ground bus bar.
8. Place ungrounded negative output cables in cable rack.
9. Insert ends of charge cables through top of rectifier and terminate
connectors on negative bus bar in rectifier. Torque to 30 Nm (240
in-lb). See Figure 5-3.
10. One at a time, remove tape or insulation from connector at other
end of charge cable and terminate on negative charge bus bar.
Warning: Battery plants are an energy hazard. Avoid arc or sparks.
Before making contact between connectors and bus bar in the next
step, use a DMM to verify a true open circuit between each
connector and known battery plant ground.
