Note When source A and source B are wired with common negative terminals, as in Figure 22, discharging does not occur
and there is no restriction requiring that source A and source B voltages be equal.
Figure 23 Connecting Source A and Source B with Common Positive Terminals
In Figure 24, source A and source B are wired with opposite polarity grounds. Do not use this configuration.
Caution Do not use the DC input configuration shown in Figure 24.
