Installation5002/11 MN05006002Z-ENConnecting the POW supply voltageThe device supply voltage for the electronics of all Smart-Wire-DT slaves (15 V DC) is generated from the 24 V DCsupply voltage that you apply to the spring-cage terminalconnection POW.Connecting the supply voltage AUXIf there are any contactors or motor starters in the Smart-Wire-DT topology, a 24 V DC voltage AUX must be addition-ally supplied as a control voltage for the contactor coils.Terminal capacities of the cables for the POW andAUX supply voltages• solid: 0.25 - 1.5 mm2 (AWG 24-16).• flexible 0.25 - 1.5 mm 2 (AWG 24-16) with appropriateisolated ferrules with plastic collars in accordance withDIN 46228, Part 4, minimum length 8 mm.h Caution!EMERGENCY STOP switching by group is performed exter-nally by switching off the 24 V DC control voltage of thecontactor coils. See also manual MN05006001Z-EN,“SmartWire-DT Slaves”h Caution!The POW power supply behaves capacitively when firstswitched on, an increased inrush current (12.5 A/6 ms)flows in comparison with the rated input current. Theswitching device and the power supply unit for switchingon the supply voltage must be suitable for this brieflyincreased inrush current.www.comoso.com
