Connect The Link Bus Cable - Nuvation Energy NUVSSG-1250-100 Product Manual

4.4.4. Connect the Link Bus Cable

The Link Bus cable is used to connect Cell Interface modules in a daisy chain (called the Link Bus
chain) by connecting the 'Link In' of one Cell Interface to the 'Link Out' of the next Cell Interface. In
this series-connected chain of modules, each connection is made from the Link In connector of the
module with higher potential to the Link Out connector of the module with lower potential.
The Link Bus provides a data channel and a power source to subsequent Cell Interface modules in the
Link Bus chain. The amount of current supplied by this connector is the sum of current consumed by
all subsequent Cell Interface modules in the Link Bus chain.
Connection Procedure
1. Connect one end of the cable to the 'Link Out' connector on the Stack Switchgear.
2. Connect the other end of the Link Bus cable to the 'Link In' connector on the Cell Interface.
3. For multiple Cell Interface modules, use additional Link Bus cables to connect the 'Link Out' on
the current Cell Interface to the 'Link In' of the next Cell Interface in the chain.
4. The 'Link Out' of the last Cell Interface module in the Link Bus chain is to be left unconnected.
