depends on the inverter usage and ambient temperature.
The operating hours can be found through P07.14 (accumulative hours of the inverter).
Fan failure can be predicted by the increasing noise from the fan bearings. If the inverter is operated
in a critical part of a process, fan replacement is recommended once these symptoms appear.
Replacement fans are available from ASTOR.
Read and follow the instructions in chapter Safety Precautions.
Ignoring the instructions would cause physical injury or death, or
damage to the equipment.
1. Stop the inverter and disconnect it from the AC power source and wait for at least the time
designated on the inverter.
2. Lever the fan holder off the drive frame with a screwdriver and lift the hinged fan holder slightly
upward from its front edge.
3. Disconnect the fan cable. Remove the installation bracket.
4. Install the bracket to the reversed direction. Pay attention the air direction of the inverter and the
fan as the figure below:
Fan installation of the inverters 1PH,230V, ≤2.2kW
Fan installation of the inverters 3PH,400V,≥4kW
6.1.2 Capacitors
Reforming the capacitors
The DC bus capacitors must be reformed according to the operation instruction if the inverter has
been stored for a long time. The storing time is counted form the producing date other than the
delivery data which has been marked in the serial number of the inverter.
