Storage
If the frequency converter is to be kept in store before use make sure that the ambient conditions
are acceptable:
Storing temperature
–40…+70
°
C
Relative humidity
<95%, no condensation
The environment should also be free from dust. If there is dust in the air the converter should be
well protected to make sure dust does not get into the converter.
If the converter is to be stored during longer periods the power should be connected to the converter
once a year and kept on for at least 2 hours. If the storage time exceeds 12 months the electrolytic
DC capacitors need to be charged with caution. Therefore, such a long storage time is not
recommended.
3.4
Maintenance
In normal conditions, Vacon NX frequency converters are maintenance-free. However, we
recommend to keep the converter clean, e.g. by cleaning the heatsink with compressed air
whenever necessary.
In IP54 units, the air filters in the door and in the roof should be cleaned or replaced regularly.
It is recommended to replace the fans every 6 years.
We recommend checking the tightening torques of terminals at regular intervals.
Vacon Service Centre can provide you with a long-period maintenance plan for your frequency
converter on request.
