Load connections are made to bullet-style distribution positions.
The distribution panel is equipped with 2 rows of 26 bullet-style distribution positions.
Top Row: 26 positions each selectable
(Panel A) between battery and –48V load output.
Bottom Row: 26 positions each selectable between
(Panel B) +24V load output and –48V load output.
