Replacing the roof-mounted fan
Inverters, frame sizes FSAA ... FSC have a roof-mounted fan. The roof-mounted fan is
located at the upper side of the inverter.
When must the roof-mounted fan be replaced?
A defective roof-mounted fan in operation results in an overtemperature condition of the
inverter. For example, the following messages indicate that a roof-mounted fan is defective:
● A30034 (overtemperature inside the enclosure)
● F30036 (overtemperature, inside area)
● A30049 (defective fan inside the enclosure)
● F30059 (defective fan inside the enclosure)
