3 Switching on DIL-SWD-32-001, DIL-SWD-32-002 contactors3.3 EngineeringSmartWire-DT modules IP20 09/17 MN05006001Z EN www.eaton.com 67The "Enable" ⑧ auxiliary contact is factory fitted with a link. If electrical locksare envisaged in the application, the bridge can be removed and a potential-free contact can be connected.The auxiliary contacts integrated in the contactor can be used, e.g. for safetyinterlocks.Two feedback inputs to the programmable logic controller are available at thethree-pole terminal of connection ⑦ for the potential-free contacts. Ifrequired, potential-free auxiliary contact contacts of the protective motorswitch PKZ can be connected to these two feedback inputs (e.g. NHI-E-…-PKZ0 standard auxiliary contacts, AGM2-…-PKZ0 differential trip-indicatingauxiliary contact).The connection terminals on the SmartWire-DT module for DILM are suitablefor cables AWG24 to AWG16 and flexible cables with a cross-section of 0.25mm2 to 1.5 mm 2.When using ferrules it has to be ensured that the ferrule length is at least 8mm.A manual or electrical ON or OFF command for the contactor can take placein addition with the aid of the 1-0-A switch ⑨ in the device version DIL-SWD-32-002.The switch positions are as follows:• 1 - Contactor ON• 0 - Contactor OFF• A - Switching command via SmartWire-DT DANGERThe "Enable" auxiliary contact must not be used for safety-related controller parts (￫ Section 3.3.3, „Safety-related appli-cations“, page 71).NOTICEThe connection cables to the potential-free auxiliary contacts atconnection X0-X1-X2 ⑦ for the potential-free contacts and atconnection X3-X4 ⑧ for the "Enable" auxiliary contact may havea maximum length of 2.8 m.￫ Use of the 1-0-A switch for the electrical switching on or off ofthe contactor is ensured only when the SmartWire-DT modulefor DILM is supplied via the SmartWire-DT connecting cable.
