10.4.2 Replace the fan unit for the heat sink
Converters, frame sizes FSA … FSF have a fan unit for the heat sink. The fan unit for the heat sink
is located at the lower side of the converter.
When must the fan unit be replaced?
A defective fan unit in operation results in an overtemperature condition of the converter. For
example, the following messages indicate that the fan unit is defective:
• A05002 (air intake overtemperature)
• A05004 (recti󹪝er overtemperature)
• F30004 (heat sink overtemperature)
• F30024 (temperature model overtemperature)
• F30025 (chip overtemperature)
• F30035 (air intake overtemperature)
• F30037 (recti󹪝er overtemperature)
