Frequency converter

WARNING! Risk of electric shock.
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! Risk of equipment damage.
No parameters in the frequency converter may be adjusted without very detailed knowledge about
the consequences. Adjustment voids the warranty.
Caution! Risk of equipment damage.
The unit is not to be started if the cooling hose has been removed.
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.
NOTE!
Figures 4C and 6 show 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.
