well as from internal or external battery cabinets.
The DC voltages are very high and dangerous (± 425Vdc).
External battery connections are performed at the right side of this panel.
The DC distribution panel on your system will have one of two possible layouts, depending on
whether your system has a maximum capacity of 50KV or 100KV. maximum capacity, as
shown in Figure 3-11.
