Battery Connection Panels
Overview
Introduction
Batteries are connected to the GPS 4848/100 cabinets based on the
system architecture.
Distributed
Architecture
For distributed power architecture, the batteries are terminated on
battery connection panels located in the cabinet directly below the ac
input panel. As options, the panels may include fuses or low battery
voltage disconnect/reconnect (LVBD/R) contactors. When equipped
with contactors, a contactor control card provides local/manual control
of the contactors.
Off Line Equalize (OLE) battery connection panels additionally provide
means to manually equalize single battery sections. A plug-in dc to dc
converter provides up to 65V to fully charge battery section cells,
equalizing cell float voltages. This restores fully charged cell capacity to
each cell in the section. A timer terminates the manually initiated
equalize operation.
Centralized
Architecture
For systems with centralized architecture, the batteries are connected
between the system charge and charge return buses. In turn, these buses
are connected to rectifier termination buses located behind the ac input
panel.
Illustrations
The battery connection panels are illustrated in Figures 6-1 through 6-6.
Note: Battery connection panels are blue; dc distribution panels are
white.
