2000 125A Ferroresonant Rectifier J85502C-1
Issue 8 July 1999
Installation 5 - 15
Initial Battery
Charging
(Optional)
Initial battery charging should be planned as part of the plant
installation. If initial battery charging is desired with the current
rectifier installation, the rectifier should be tested before
following this procedure (see Section 6, “Testing”).
The J85502C-1 rectifier is capable of supplying a new battery
string with its initial charge. Since the voltage levels
recommended by battery manufacturers for initial battery
charging are considerably above the normal plant voltage,
neither the battery nor the rectifier used to supply its initial
charge should be connected to the rest of the plant during this
procedure. One rectifier should be sufficient to supply the
charge. However, the high voltage shutdown levels must be
raised to accomplish the initial charge. The following procedure
describes how to raise the high voltage shutdown levels.
