3.5.Connecting the dc output terminals to the busbars

The dc outputs of the rectifier are connected to the busbars as illustrated in Figure 5. There are two methods :

•BAT GRD ( + ) of the rectifier connected to the CHG/ DISCH GRD busbar and the –48 V of the rectifier connected to the CHG BAT busbar

•BAT GRD ( + ) of the rectifier connected to the CHG GRD busbar and the -48V of the rectifier connected to the CHG/ DISCH BAT busbar
