The illustration in figure 1-5 shows a dedicated battery installation for each
module; however, it is possible to fit an option kit which allows the two
modules in a one-plus-one system to share a common battery. Such an
installation is shown in figure 1-6 overleaf.
Note: the "Common battery" configuration is possible with 6 pulse
rectifiers only, not with 12 pulse rectifiers.
