If electrical locksare envisaged in the application, the bridge can be removed and a potential-free contact can be connected.The auxiliary switches integrated into the contactor can be used, for exam-ple, as safety locking devices.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-DTATTENTIONThe SmartWire-DT module for DILM drives the contactor so thatterminals A1-A2 must no longer be wired. DANGERThe "Enable" auxiliary contact must not be used for safety-related controller parts (￫ Section 3.3.3, „Safety-related appli-cations“, page 73).ATTENTIONThe 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.
