Recharge baƩery. Check connecƟons and cable. Allow inverter to cool off. Reduce load, conƟnuous operaƟon input current required. Improve venƟlaƟon; make sure venƟlaƟon openings in the inverter are not obstructed. Reduce ambient temperature. Make sure the inverter is connected to 12V baƩery. Check regulaƟon or charging system. Check load for proper operaƟon. Turn inverter on. Check wiring to inverter. Observe correct polarity. Check connecƟons. Make sure baƩery is fully charged. 17 | P a g e
