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.

• 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 4 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
