Servicing The Capacitors; Capacitor Reforming - ABB ACS380 Hardware Manual

Maintenance 85

Servicing the capacitors

The intermediate DC circuit of the drive has electrolytic capacitors. Their lifespan
depends on the operating time and loading of the drive, and the surrounding air
temperature.
Capacitor failure can cause damage to the drive and an input cable fuse failure, or a
fault in the drive. Contact ABB if you think that a capacitor failed. You can get spare
parts from ABB. Use only ABB specified spare parts.


Capacitor reforming

You must reform the capacitors if the drive is stored for a year or more. Refer to Drive
labels on page 33 to read the manufacturing date from the serial number.
To reform the capacitors, refer to Converter module capacitor reforming instructions
(3BFE64059629), available on the Internet (go to www.abb.com and enter the code in
the Search field).
