4.4.2. Link In
The Link In connector provides power and communication to this Cell Interface from the Cell Interface
modules below this Cell Interface, or from the Stack Controller if this Cell Interface is measuring the
most negative cell in the stack.
The amount of current sourced into this connector is the sum of current consumed by this Cell
Interface and all those above it (which amounts to all Cell Interface modules if this Cell Interface is
measuring Cell 1).
Connect to the Link Out connector on the Cell Interface that is measuring the previous series-
connected cell below this Cell Interface to this connector, or connect the Stack Controller to this
connector if this Cell Interface is measuring the bottom cell in the stack.
