USB-C interface
The ETU600 electronic trip unit has a USB-C interface on the front. The electronic trip unit can
be activated and parameterized via this interface.
An overview of the interfaces on the front can be found in Chapter Overview (Page 70).
The SENTRON powerconfig configuration software can be used for support. The current
version of the SENTRON powerconfig configuration software can be found on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/63452759
).
ETU600 activation requires that the interface (USB port, USB power supply unit, power bank)
can supply a current of 1.5 A or more.
Note
Using the USB-C interface
The USB-C interface of the ETU600 is designed for temporary use during commissioning,
maintenance or service. No USB cable may be connected to the interface during normal
operation. The Bluetooth interface makes local access possible during operation.
Bluetooth interface
Parameterization of the ETU is also possible via the integrated Bluetooth interface.
Note
Bluetooth is deactivated in the 3WA circuit breaker on delivery. Bluetooth can be activated via
communication, the display of the ETU600 electronic trip unit or the USB-C interface.
Bluetooth is automatically deactivated when the communication is interrupted and after a
timeout.
Bluetooth certifications can be found on the Internet
