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.
