Connecting the POW supply voltage
The device supply voltage for the electronics of all Smart-
Wire-DT slaves (15 V DC) is generated from the 24 V DC
supply voltage that you apply to the spring-cage terminal
connection POW.
Connecting the supply voltage AUX
If 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 and
AUX supply voltages
• solid: 0.25 - 1.5 mm
2
(AWG 24-16).
• flexible 0.25 - 1.5 mm
2
(AWG 24-16) with appropriate
isolated ferrules with plastic collars in accordance with
DIN 46228, Part 4, minimum length 8 mm.

Caution!
EMERGENCY STOP switching by group is performed exter-
nally by switching off the 24 V DC control voltage of the
contactor coils. See also manual MN05006001Z-EN,
“SmartWire-DT Slaves”
h
Caution!
The POW power supply behaves capacitively when first
switched on, an increased inrush current (12.5 A/6 ms)
flows in comparison with the rated input current. The
switching device and the power supply unit for switching
on the supply voltage must be suitable for this briefly
increased inrush current.
