Earth Fault Level sets the sensitivity threshold for detecting ground leakage current, with options for low or high sensitivity detection. The manual's first action is: “Note: Parameter 3017 EARTH FAULT has to be enabled. 1 = LOW – Low level leakage current, high sensitivity. The drive trips to low ground (earth) leakage current (default in the USA software version). 2 = MEDIUM – Medium sensitivity to ground (earth) fault current (default in the European software version). 3 = HIGH – High level leakage current, low sensitivity. The drive trips to higher ground (earth) leakage current.”
