Frequency converter

WARNING!
The frequency converter is not to be opened until 5 minutes after the supply voltage has
been disconnected. The capacitors inside the converter hold a very dangerous voltage until
they have discharged themselves.
CAUTION!
•
Do not adjust any parameters in the frequency converter without written authorisation
from the person responsible for this product. See the Declaration of Conformity. Any
unauthorised adjustment may void the warranty.
•
The unit is not to be started if the cooling hose has been removed.
NOTE! Figure 4 shows the cooling air hose that improves the cooling of the frequency
converter.
NOTE! For parameter settings in the frequency converter, see the 'FlexPAK Frequency
Converter Parameter Table' that is a separate document included with the unit.
The frequency converter controls the unit's motor so that it operates efficiently, as well
as maintaining the unit's vacuum level to help prevent a dangerous underpressure from
developing. The manual for the frequency converter is enclosed.
