environments where the air contains high concentrations of dust or metallic particles. Select
a well ventilated location for storing the inverter.
2.
If the inverter is to be stored for prolonged periods, you should schedule regular sessions for
energizing the inverter's circuits. This is necessary to assure that inverters circuitry will remain
operaitonal. Stored inverters should be energized and tested at least once every two years, to
ensure that its large electrolytic capacitors are recharged.

degraded if they are stored for too long with no regular energization of the inverter. After
removing an inverter from prolonged storage, energize it with electricity for at least five hours
before attempting to run a motor with the inverter.
