DC power lights up the surge protector’s DC ACTIVE LED

AC OUTPUT from the FX will light up the AC OUT ACTIVE LED

AC INPUT from a utility grid or generator will light the AC IN ACTIVE LED

Initially, if any ERROR LED lights, check all wiring and inspect the surge protector circuit board for damage. If no damage or wiring problems are found but the ERROR light stays lit, please contact OutBack Technical Services

Check the surge protector periodically and particularly after any suspected surge event. If an ERROR occurs, replace the board with an FW-SP-R or contact OutBack Technical Services
