3.2 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
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.
3.3 Maintenance
In normal conditions, Vacon NX frequency converters are maintenance-free. However, we recommend to
clean the heatsink with compressed air whenever necessary.
The cooling fan can easily be changed if necessary.
It may also be necessary to check the tightening torques of terminals at certain intervals.
3.4 Warranty
Only manufacturing defects are covered by the warranty. The manufacturer assumes no responsibility for
damages caused during or resulting from transport, receipt of the delivery, installation, commissioning or
use.
The manufacturer shall in no event and under no circumstances be held responsible for damages and
failures resulting from misuse, wrong installation, unacceptable ambient temperature, dust, corrosive
substances or operation outside the rated specifications.
Neither can the manufacturer be held responsible for consequential damages.
The Manufacturer's time of warranty is 18 months from the delivery or 12 months from the commissioning
whichever expires first (Vacon Warranty Terms).
The local distributor may grant a warranty time different from the above. This warranty time shall be
specified in the distributor's sales and warranty terms. Vacon assumes no responsibility for any other
warranties than that granted by Vacon itself.
In all matters concerning the warranty, please contact first your distributor.
