3.10 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
• Do not adjust any parameters in the fre-
quency converter without written author-
isation from the person responsible for this
product. See the . Any unauthorised adjust-
ment may void the warranty.
• The unit is not to be started if the cooling
hose has been removed.
Figure 4C shows the cooling air hose that im-
proves the cooling of the frequency converter.
For parameter settings in the frequency con-
verter, 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

derpressure from developing. The manual for the fre-
quency converter is enclosed.
