7. Power Shield

If a Power Shelf is not fully populated, Power Shields are used to cover unused spare slots.

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 ribbon cable should be tied back and left unused.
