6. Maintenance
In general, the rectifier is maintenance-free. Exclusively the fan is a component consisting of moving
parts. By way of precaution a yearly inspection with following checks is recommended:
Mechanical/visual inspection
Removal of dust and dirt, especially on radiator surfaces
Check for internal dust or humidity
It is recommended to exchange the fan every five years.
Attention! Dust combined with moisture or water may influence or destroy the internal electronic
circuits.
Dust inside the unit can be blown out with dry compressed air.
The interval between the checks depends on ambient conditions of the installed module.
