Proline 5000™ Inverter by Wagan Tech®15www.wagan.com• Coil the television power cord or install a clamp-on ferrite choke (available from electronicparts suppliers).Note: Some inexpensive audio systems may have a slight “buzzing” sound when operated withthe inverter. This is caused by insufficient filtering in the audio system. The only solution to thisproblem is to get a sound system with a higher quality power supply.TROUBLESHOOTINGPROBLEM: Low or no output voltageReason SolutionPoor contact with battery terminals Clean terminals thoroughlyUsing incorrect type of voltmeter to testoutput voltageUse true RMS reading meterPROBLEM: Inverter is shut downReason SolutionBattery voltage below rated value. Recharge or replace batteryEquipment being operated draws too muchpowerCable gauge may be inadequate—use heaviercablesInverter is too hot (thermal shut down mode) Allow inverter to coolCheck for adequate ventilation.Reduce the load on the inverter to rated continuouspower outputUnit may be defective See warranty and call customer servicePROBLEM: TV/audio interferenceReason SolutionElectrical interference from the inverter Add a ferrite data line filter on to the TVpower cordPROBLEM: Low battery alarm on all the timeReason SolutionInput voltage below rated value. Increase input voltage m aintain regulation.Poor or weak battery condition Recharge or replace batteryPoor or loose cable connection Inspect terminals and tighten all connectionsInadequate power being delivered to theinverter or excessive voltage dropUse lower gauge wireKeep wire length as short as possible
