2000 25A Ferroresonant Rectifier J85502A-1
Issue 4 May 1998
Installation 5 - 7
4. Install two input conductors and frame ground conductor
at the ac service panel, and route the conductors to the
rectifier.
5. Strip the ends of conductors that will be installed in the
rectifier.
6. Secure conductors and frame ground in rectifier. First,
connect the ground lead to its termination point marked
FR GRD near the ac input hole. Connect the input
conductors to TB1 according to the section on “Converting
AC Voltage” and torque to 16 in-lb.
7. Verify that the branch circuit breaker to the rectifier in the
ac service panel is Off or fuses are removed. Reenergize ac
service panel. Tag branch circuit breaker or fuse holders to
inform others not to close (turn On) the ac breaker or insert
ac fuses. If the branch circuit (two input conductors and
frame ground) is protected by fuses, physically remove the
fuses from the area of the ac service panel.
Installing DC
Power Cables
Plant bus bars may carry 52 volts dc. Observe DANGER
warnings in Section 4.
Use Figures 5-1 and 5-2 as references for this section.
1. Turn DC OUTPUT circuit breaker on rectifier Off
(down).
2. Measure the lengths required for the two dc output cables:
one to run the output from the rectifier to its termination
point on the plant charge bus bar, and one to run the dc
return (ground) from the rectifier to its termination point
on the plant ground bus bar.
3. Cut cables to length and strip the ends of cables that will be
installed in the rectifier.
4. Tape or otherwise insulate connectors on the ends of
cables that do not terminate in the rectifier.
5. Place dc return cable in cable rack.
6. Thread end of return cable through the right side of
rectifier and attach connector to the appropriate terminal
