2000 50A Ferroresonant Rectifier J85502B-1
8 - 18 Spare Parts and Replacement Procedures

7. Rotate the top of capacitor/bus bar assembly forward until
capacitor terminal screws (through bus bars) can be
accessed.
8. Noting their connection points, remove screws holding
desired capacitor(s).
9. During reinstallation, use caution when reinstalling leads
to capacitors to avoid stripping the threaded copper
capacitor terminals. Insure capacitor is being installed with
the proper polarity.
Rear
Compartment
Components: AC
Inductor L1, AC
Capacitor C5,
DC Inductor L2,
AC Contactor
K3, Transformer
T2, and Relay K2
All components in the rear compartment of the J85502B-l
rectifier are accessible by removing the top and rear covers.
Follow the procedure for “Disconnecting a Rectifier” in this
section in order to remove a rectifier from a frame, if necessary,
to remove these covers.
The following points should be noted:
•
To facilitate replacement, note the positions of all
quick-disconnect and other leads or header connectors
before removing.
•
In the case of the dc inductor L2, one of the leads goes to the
front compartment and terminates on a dc capacitor
terminal. The entire dc capacitor removal procedure (see
DC Filter Capacitors) must be performed prior to removing
the dc inductor in order to disconnect this lead.
•
In order to remove T2, the header connector P4 on the CM1
option board (front compartment) must be disconnected and
passed through hole 2 (H2) to the rear compartment. (The
leads from T2 connect to P4.) It may be necessary to cut a
cable tie before P4 can be passed through to the rear
compartment.
•
Early production models of the J85502B-1 rectifier without
208/240 Vac switch S3 have an ac contactor that is
designated K1. Newer production rectifiers, containing S3,
have a contactor that is designated K3.
