Capacitors; Reforming; Leds - ABB ACS800 Series Hardware Manual

Capacitors

The drive intermediate circuit employs several electrolytic capacitors. The lifespan
depends on drive loading and ambient temperature. Capacitor life can be prolonged
by lowering the ambient temperature.
It is not possible to predict a capacitor failure. Capacitor failure is usually followed by
a mains fuse failure or a fault trip. Contact ABB if capacitor failure is suspected.
Replacements for frame size R4 and up are available from ABB. Do not use other
than ABB specified spare parts.

Reforming

Reform (re-age) spare part capacitors once a year according to Converter modules
with electrolytic DC capacitors in the DC link, Capacitor reforming instructions
(3BFE64059629 [English]).
