Note
You might need to access the information provided on the side-mounted type plate after the
equipment has been mounted. Since the type plate is located on the right-hand side of the
housing, which is the side typically used to connect to the SINAMICS S120 module, we
recommend that you make a note of the serial number of the NX prior to assembly.
