3.4.5 Control section power supply
The control section in the DS7 soft starter can be powered with the following
voltages using terU
s
/-U
s
(sizes 2, 3, and 4) or +U
s
/-A2 (size 1):
•
24 V DC/AC at DS7-34
0
…
•
120 - 230 V AC at DS7-34

•
24 V DC at DS7-34

DS7-34D…-D soft starters can be powered directly through the
SmartWire-DT ribbon cable.
3.4.6 Internal device voltages
The DS7 soft starters do not provide any internal voltage.
3.4.7 Ground control voltage
All control signal terminals of the DS7 soft starter are galvanically isolated
from the power section. Connecting the control voltage on the DS7 soft
starter to earth is not necessary.
→
At a high load on the PSU supplying the SWD (many modules,
signaling lamps, soft starters) soft starter DS7 can also be
supplied with control voltage through control signal terminals U
s
or further SmartWire-DT PSUs (gateway EU5C-SWD-PF…).
If power is fed through control signal terminals U
s
the 24 V
connection on the SWD gateway must be switched off.
→
Ensure that the regulator supply voltage and the control signals
always have the same potential and are supplied from the same
voltage source.
NOTICE
In size 1 devices, connection terU
s
, +A1, and 13
(via the TOR contact) have a common reference potential (-A2).
The switched voltage (TOR) and the control voltages (+U
s
, +A1)
must
be the same here!
→
If control voltage earthing requirements must be complied with
(e.g., Safety of machinery - Electrical equipment of machines,
EN 60204) earthing must be implemented at the power supply
source (control transformer, power supply unit).
