Maintenance 

Very little maintenance is required to keep the inverter operating 

properly. The exterior of the unit should be cleaned periodically 

with a damp cloth to prevent accumulation of dust and dirt. At the 

same time, tighten the screws on the DC input terminals. Be sure 

vents and fans are free of dust or debris.
