•
Protect the converter from excessive mechanical vibrations in the electrical box.
• Check that the main supply and the nominal current are coherent with the rating of the drive. Be
sure that the voltage between the connectors L1-L2-L3 is not greater than 10% of the nominal values.
An excessively high voltage causes the breakdown of the load circuitry and of the drive.
• The
minimagnum
TM
is equipped with an integrated
EMI anti-disturbance filter
at the 3-phase power
supply input and with another EMI anti-disturbance filter at the aux24V power supply input.
Being implicit to filter operation the deviation towards earth or mass of the undesired frequencies,
ensure that these devices can produce leakage currents towards earth, which are measurable in mil-
liAmpers. Please remember that "leakage currents" must be considered when settings differential
devices in order to avoid useless interventions.
For safety reasons connect the prepared terminal to earth before powering the drive. Incorrect con-
nections make filter operation unreliable.
