This inter-relationship is provided to minimize incorrectly setting parameters. A brief
explanation is provided in the Figure 6-21.

Hi Lmt
When the input utility line exceeds this voltage setting the
BBS will transfer to Battery Mode from Line Mode or Buck
Mode.

When the input utility line drops below this voltage setting
the BBS will transfer to Battery Mode from Line Mode or
Boost Mode.
