EARTH CONNECTION
• Ground the drive and adjoining cabinets to ensure a safe operation and
to reduce electromagnetic emission.
• Connect the input PE terminal only to the dedicated PE terminal of the
drive. Do not use the case, nor chassis screws for grounding.
• Ground the drive chassis through the labelled terminals. Use
appropriate conductors to comply with local regulations. The ground
conductor should be connected first and removed last.
• Motor ground cable must be connected to the PE output terminal of the
drive and not to the installation’s ground. We recommend that the
section of the ground conductor (PE) is equal or greater than the active
conductor (U, V, W).
TRIAL RUN
• Verify all parameters before operating the drive. Alteration of
parameters may be required depending on application and load.
• Always apply voltage and current signals to each terminal that are within
the levels indicated in this manual. Otherwise, damage to the drive may
occur.
CAPACITORS DEPLETION
If the drive has not been operated for a long time, capacitors lose their
charging characteristics and are depleted. To prevent depletion, once a year
run the device under no-load conditions during 30-60 minutes. For further
information, please contact Power Electronics.
