8. Power Shelf Interconnect
A ribbon cable is required to connect Power Shelves together in order to current share, or to
connect shelves to a Power Controller.
The supplied ribbon cable has 5 connectors, to allow the maximum of 4 Shelves and a Power
Controller to be connected.
Do not connect the TC-323 cable between ‘A’ and ‘B’ supplies or between two sets of
Shelves which connect to separate busbars. The supplies will attempt to share current
between the two busbars, which may damage the Power Packs and Shelves’ sensing circuits.
Unused connectors on the TC-323 cable should be tied back and left unused.
