The Siemens 6SL3256-1BA00-4HB0 is an Operator Panel Extension cable designed specifically for the SINAMICS G120P drive series in IP55 enclosures. It connects the drive's basic operator panel (BOP) or intelligent operator panel (IOP) to the control unit when the panel is mounted remotely, such as on an enclosure door. This keeps the operator interface accessible without opening the IP55-rated cabinet.
What the description tells you about fit
The description specifies Operator Panel Extension cable for G120P IP55. That IP55 rating means the drive end of this cable mates with a sealed, washdown-rated enclosure. The cable itself is a factory-assembled harness with the correct connector pinout for the G120P control unit and the panel-mount operator station. If you are retrofitting a G120P that came without the remote panel option, this is the OEM cable — no adapter or field-wiring needed.
