ABB low voltage AC drives This manual applies to drive, inverter, IGBT supply and three-phase brake modules in product series ACS800, ACS850, ACQ810, ACSM1, ACS380, ACH480, ACS480, ACH580, ACQ580, ACS580 and ACS880, that is, the following module types: •...
This manual applies to line-side converter modules and generator-side converter modules in product series ACS800-67LC, ACS800-77LC, ACS800-87LC and ACS800N-87LC. Note: ACS800-67 and ACS800-77 modules include film capacitors in the DC link instead of electrolytic capacitors.The film capacitors do not need to be reformed.

Introduction 7 4. Make sure that the converter is clean and dry (no condensation) before you start the reforming.
If the converter has been non-operational for less than one year, the capacitors do not need reforming. Besides the reforming methods presented in this manual, ABB can supply you with ready- made reforming devices, such as FINERO FST-DCP 1500-05 and FUG HCK 800-2000.

This method can be used for capacitor reforming if the converter has been stocked (non- operational) for one to two years (product series ACS800, ACS850, ACQ810, ACSM1, ACS880-104, ACS380, ACH480 and ACS480) or for one to three years (product series ACH580, ACQ580, ACS580 and ACS880 except ACS880-104).
