Form factor and what it does
The 6SL5166-1AH00-0AA0 is a SINAMICS S220 shield connection plate sized for the 200 mm booksize motor and line module. It sits across the power cable shield landings of the booksize converter, giving the cable screen a defined, low-impedance bond back to the module chassis so common-mode current on the motor leads has a controlled path rather than radiating into the cabinet.
Ordering codes on the label
Group Code R220 and Product Group X0HX are the internal Siemens classification tags carried on this line — they line the part up with the SINAMICS S220 booksize accessories in the Siemens ordering system and are how the configuration tool expects the shield plate to be referenced against the host motor or line module. The shield plate is classed as a made-to-order item that cannot be returned for credit, and ships as one piece per package — so it belongs on a configuration line, not in a returns bin.
