2 I/O modules EU5E-SWD…2.9 Digital module EU5E-SWD-4D4D-RSmartWire-DT module IP20 01/20 MN05006001Z-EN www.eaton.com 37Precondition:• There must be 24 VDC at Upow on the gateway• If EU5C-SWD-PF..-1 power feeder modules are installed upstream of theI/O module but downstream of the gateway, they must also be poweredvia the Upow terminal.• There must be 24 VDC at the 0 V, 24 V terminals on the I/O module inorder to power the outputs• The output channels must be configured appropriatelyCondition for disconnection:• The 24 VDC at the I/O module (power for outputs) being removed -> Noenergy for driving the downstream contactors. However, the outputsremain logically "switched" and would remain on when the power isrestored.• The Upow 24 V at the coordinator (gateway) or EU5C-SWD-PF2-1 modulebeing switched off. This would cause the module to lose its operatingvoltage (15 V) and no longer be able to drive the outputs. After switchingthe power back on, the outputs would remain off.• The configuration button on the gateway being pressed or the corre-sponding function being run in SWD-Assist, triggering a new configura-tion import as a result. In this case, SmartWire-DT would restart and theswitched outputs would be switched off for a brief moment (a few 100ms).• Loading a new PLC configuration with modified parameters.Figure 15: Connecting inputs/outputs and power supply DANGERAs a result of unintended actuation!When a project is transferred to a controller, it will have animmediate effect on the controller's ongoing operation.This may result in errors in the process being controlled. Thesafety mechanisms being used on site must not be disabled asa result of a project being transferred.0 V24 V DC24 V0 V1 2 30Q1 2 30IQ1Q0Q3Q2I1I0I3I2
