Commissioning and initial set-up
Initial power-up of the frequency converter should be performed with the
motor disconnected (disconnected output power cables). After energizing
the input power circuit and powering up the frequency converter, please
make sure there are no faults and that the frequency converter is in the
«STOP» mode. In the event of faults, please refer to the technical and
operation manual.
WARNING!
If the frequency converter has been out of operation for an extended
time (over 6 months), or if there has been a delay of more than 6 months
between the converter delivery and initial power-up, please power up the
converter with output power cables disconnected and keep it energized
for one hour. The frequency converter should remain in the «STOP» mode
for the duration of this period. This is required to properly reform the DC
capacitors of the frequency converter.
