QS Link Power Distribution
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 Power Draw Units (PDUs) on the QS Link Specification Submittal (Lutron P/N
369405) at www.lutron.com for more information regarding 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. See Wiring section on the previous page for details on wiring the QSPS-DH-1-75
power supply to the QS link.
