Capacitors - ABB ACS880-17 Hardware Manual

7. Attach the lifting lugs of the module to be removed to the cabinet lifting lug with
chains.
8. Pull the LCL filter module carefully out of the cabinet preferably with help from another
person.
9. Install new module in reverse order.

Capacitors

The DC circuit of the drive modules of the drive contain several electrolytic capacitors.
Their lifespan depends on the operating time of the drive, loading and ambient
temperature. Capacitor life can be prolonged by lowering the ambient temperature.
Capacitor failure is usually followed by damage to the unit and an input cable fuse failure,
or a fault trip. Contact ABB if capacitor failure is suspected. Replacements are available
from ABB. Do not use other than ABB-specified spare parts.
Reforming the capacitors

The capacitors must be reformed if the drive not been powered (either in storage or
unused) for a year or more. See page
date. For information on reforming the capacitors, see Converter module capacitor
reforming instructions (3BFE64059629 [English]).
