SECTION 11 | Trouble Shooting GuideISSUE POSSIBLE CAUSE REMEDYThere is no AC output. TheGREEN "Power ON" LED(2) is lighted. Buzzer is on.GREEN indication light on theGFCI is OFF.AC output shuts down completely.Red "Overload" LED(3) is lighted. Buzzer is ON.The GREEN "Power ON" LED(2) is lighted. GREEN indicationlight on the GFCI is OFF.There is no AC output. Buzzeralarm is sounded. Red "Overtemperature" LED (4) islighted. The GREEN "PowerON LED (2) is lighted. GREENindication light on the GFCIis OFF.There is no AC output.GREEN indication on the GFCIis OFF. The GREEN "PowerON" LED (2) is lighted. Nobuzzer alarm.Shut-down due to highinput DC voltage –> 16.5V for 12V versionsand > 33V for 24Vversions.Permanent shut-down ofthe AC output due to continuousoverload beyondthe continuous powerrating of the inverter.Shut-down due to overtemperature because offan failure or inadequatecooling as a result of highambient temperature orinsufficient air exchangeGFCI has tripped due toleakaage or due to Neutralto Ground bond on theload side.Check that the voltage at the DC input terminalsis less than 16.5V for 12V versions and lessthan 33V for 24V versions.Ensure that the maximum charging voltage ofthe battery charger / alternator / solar chargecontroller is below 16.5V for 12V versions andbelow 33V for 24V versions.Ensure that an unregulated solar panel is notused to charge a battery. Under cold ambienttemperatures, the output of the solar panelmay exceed 22V for 12V system or 42V for24 V system. Ensure that a charge controller isused between the solar panel and the battery.Reduce the load.The load is not suitable as it requires higherpower to operate. Use an inverter with higherpower rating.If the unit goes into permanent overload againafter resetting and removing the load completely,the unit has become defective.Call Technical support.Note: The unit will be latched in this shutdowncondition and will require manual reset.To reset, switch off the powerOn/Off switch, wait for 3 minutes and thenswitch on again.Before switching on again, remove the causeof the shut-down.Check that the fans are working. If not, the fancontrol circuit may be defective. CallTechnical Support.If the fans are working, check that the ventilationslots on the suction side and the openingson the discharge side of the fans are notobstructed.If the fans are working and the openingsare not obstructed, check that enough coolreplacement air is available. Also check that theambient air temperature is less than 40ºC.Reduce the load to reduce the heating effect.After the cause of overheating is removed andthe unit cools down sufficiently, it will resetautomatically.Check load side circuits for leakage or Neutralto Ground bonding and correct. Press "ResetButton" on the GFCI to reset. Ensure that theinverter is ON before re-setting.SAMLEX AMERICA INC. | 41
