2000 25A Ferroresonant Rectifier J85502A-1
6 - 4 Testing
Issue 4 May 1998
7. Disconnect J2A from CM2 by unlatching first, then
pulling the cable connector.
8. Connect the test load to the + and - output terminals on
TB3 in the rectifier.
9. Install the regulation (REG) fuse associated with the
rectifier in the plant controller.
10. When you are ready to power the test load, you must
restore ac to the rectifier at the ac service panel, turn On
the rectifier POWER switch, and turn On the DC
OUTPUT circuit breaker. If this is initial testing, check
the control cable first (see “Preparation for Testing Off
Line”).
Preparation for
Testing Off
Line
The following steps check the plant control cable and prepare the
equipment for testing.
1. Verify that the ac supply and rectifier controls are as
shown in Table 6-A.
2. Use the documentation for the particular battery plant to
perform all the preliminary checks on the plant prior to the
rectifier tests. If the rectifier is in a
microprocessor-controlled plant with an efficiency
algorithm feature, disable this feature. (See the controller
manual for instructions.)
