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 has to be supplied
as a control voltage for the contactor coils.
Connecting the POW supply voltage
EU5C-SWD-PF2: the device supply voltage for the electronics
of all SmartWire-DT slaves (15 V DC) is generated from the
24 V DC supply voltage that you apply to the spring-cage
terminal connection POW.
Terminal capacities of the cables for the POW and
AUX supply voltages
• solid: 0.2 - 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!
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.
