Note
To achieve better EMC performance, Siemens recommends that you
observe the following when connecting the device:
• Use the shielded cable for RS232 communication between the
converter and the device.
• Do not connect the device to the ground via the PE terminal (pin 1 at
X121, pin 17 at X122).
• Route the signal cables and the power cables separately in different
cable conduits.

2.4 Identifying the converter (optional)
The SINAMICS CONNECT supports port modes of "Auto" and "Manual"
which you can set via the SINAMICS CONNECT Web server. For more
information, see Section "Configuring ports" in the SINAMICS
CONNECT Operating Instructions.
• Auto (default): Keep pressing the USER button for no more than
1 second to identify the converter at the port, or wait (up to 5
minutes) for the device to identify the converter.
• Manual: You must set the basic parameters of the converter
manually via the Web server.
