REX640 Modification Sales Guideline

The modification package contains hardware and software or software only for one or several relays. By default the modifications for several relays within a single request are delivered as a single package containing the required licenses, software and related hardware. If the delivery should be split into several packages, ABB must be informed within the request for quotation.

Licenses and software are delivered on a USB memory stick containing a software package (.zip file), modification instructions and HMI software (.cab file). If necessary, licenses and software can be delivered, for example, via email. The delivery address (postal and email) must be confirmed during the quotation process.

The guarantee period for the delivered hardware is the same as originally given for the relay for which the modification is installed. The guarantee period for the Modification Sales delivery starts on the date it is dispatched from the factory.
