8.6.2 Input Terminals
Interconnection bus bars are connected between DC+ bus bars. This link
combines single DC links parallel. Bus bars are used to end of year 1999.
Beginning of year 2000 DC+ terminals are replaced with wider model where
all DC+ wires are connected.
Older model’s interconnection is not done. Recommended to add during
service. This action smooth current sharing between sections.
