The Siemens 6SL3255-0AA00-2CA0 is a PC inverter connection kit 2 for the SINAMICS G120 drive family. It includes a 3-meter USB cable to link a laptop or PC to the Control Unit for commissioning, parameterization, and diagnostics via Siemens Starter or Startdrive software.
The kit is specified for the following SINAMICS G120 Control Units: CU230P-2, CU240B-2, CU240E-2, CU250S-2, as well as the G110M and SINAMICS G120C drives. The USB cable plugs into the mini-USB port on the front of the Control Unit; the other end is a standard USB-A connector for the PC. No external power supply is needed — the Control Unit provides bus power over the USB connection.
Deployment Context
This is a commissioning and service tool, not a permanent panel component. The 3-meter cable length gives enough reach to set the laptop on a nearby workbench or cart while the drive is powered up inside the cabinet. For permanent PC-to-drive links, a PROFIBUS or PROFINET connection would be the standard choice; this kit is for temporary engineering access.
