Warranty The Delta E series grid-tied inverter includes a standard 10-year warranty in effect from the time your inverter is commissioned. For all the Delta E series NA warranty terms and return procedures, please refer to our web site at http://www.delta-americas.com/SolarInverters.aspx for further infor- mation. - Page 58 Abbreviation for “Direct Current”. The Electro-Magnetic Compatibility (EMC) concerns the technical and legal basics of the mutual influencing of electrical devices through electromagnetic fields caused by them in electrical engi- neering. FCC is the abbreviation for Federal Communications Commission. Galvanic isolation No conductive connection between two component parts.
- Page 59 Nominal current Nominal current is the absorbed current in case of electrical devices if the device is supplied with the nominal voltage and yields its nominal power. In electric systems and cables a protective earth conductor is frequently employed. This is also called grounding wire, protective grounding device, soil, grounding or PE (English „protective earth“).
