Intelligent Technologies QCPort System Install ManualNovember 2005MN05001002E For more information visit www.eatonelectrical.com Page 17Application ExampleFigure 11: Distributed Motor Control PanelIn this Distributed Motor Panel application example, there are two types of interconnectmedia being used. The IO and Network Adapter use the Backplane Interconnect whilethe motor starters use the QCPort Interconnect cables. In this example, the QCPortpower is supplied through the D77E-QPLR biasing resistor (last module), and the changefrom the backplane to the QCPort Interconnect cable is performed there as well.When powering the QCPort system, the power supply that provides power to the startersis the same power supply that provides power to the QCPort system. It is important tosize the power supply for the load of the starters and the QCPort load in this application.Another configuration would include an Automation power supply for the QCPortcomponents only, and a separate power supply for the IT starters.All the devices within this example can and will work as designed using one powersupply. For reasons of isolation, a separate DeviceNet power supply would be requiredto power the DeviceNet products.IT. 24V DCPower Supply
