After a longer storage time the capacitors need to be recharge in order to
avoid capacitor damage. Possible high leakage current through the capac-
itors must be limited. The best way to achieve this is to use a DC-power
supply with adjustable current limit.
1. Set the current limit to 300...800 mA according to the size of the drive.
2. Then connect the DC-power supply to the input phase L1 and L2.
3. Then set the DC-voltage to the nominal DC- voltage level of the
(1.35 × Un AC) and supply the converter for at least 1h.If DC-voltage
is not available and the unit has been stored much longer than 12
months de-energized, consult the factory before connecting power.
