.
The 8-pin SmartWire-DT ribbon cable carries not only the communication
signal, but also a 24 V DC U
AUX
voltage used to power and control the
electronic motor starter.
1.5.2 Mains connection
Use terminal 3, which is the terminal for the three-phase input voltage, to
connect the unit to the three-phase supply system. If you are using an EMS
reversing starter, make absolutely sure to pay attention to the terminal
names for the EMS-DOS/ROS-SWD unit when connecting the unit to the
three-phase supply system so that you will be setting the correct direction of
rotation for the motor. Finally, connect the motor being driven to terminal 8,
i.e., the three-phase output voltage terminal.
1.5.3 Status LEDs
Electronic motor starter EMS-DOS/ROS-SWD uses four LEDs to indicate its
operating state.
These LEDs have the following designations and colors:
