Reforming the capacitors

The capacitors must be reformed if the drive has not been powered (either in storage or
unused) for a year or more. The manufacturing date is on the type designation label. For
information on reforming the capacitors, see Converter module capacitor reforming
instructions (3BFE64059629 [English]) in the ABB Library (https://library.abb.com/en).
If the drive module has been stored for one to three years, turn on the mains power for 30
minutes without load, then continue as usual.
If the drive module has been stored for less than a year, continue as usual.
