Power Group Wiring Example
On the QS link, there are devices that supply power and devices that consume power. Each device has a
specific number of Power Draw Units (PDUs) it either supplies or consumes. A Power Group consists of one
device that supplies power and one or more devices that consume power; each Power Group may have
only one power-supplying device. Refer to the QS Link Power Draw Units specification submittal
(Lutron P/N 369405) for more information concerning PDUs.
Within Power Groups on the QS link, connect all 4 terminals (1, 2, 3, and 4), shown by the letter A in the
diagram. Between devices on the QS link that supply power, connect only terminals 1, 3, and 4 (NOT
terminal 2), shown by the letter B on the diagram.
Wiring can be T-tapped or daisy-chained.
