On your device there is usually a sticker next to the nameplate with a 2D bar code and the serial number (7-digit alphanumeric, i.e. numbers and capital letters).

The serial number on the sticker shown here is only an example!

On your product you will usually find the type plate near the motor / drive unit. There you can find the 7-digit article number and the 5-digit identification number. The item number is also shown on the manuals.
