Spare part identity and fit
The 6SL3500-0XB51-0AA0 is the on-site operating unit for the SINAMICS G115D wall-mounted drive variant. It ships as a single piece, including the operating unit and key, per the spare part description. This is not a full drive — it is the HMI panel that mounts on the drive enclosure, intended for field replacement when the original unit is damaged or missing.
