Replacement (R6)

Remove the top cover by lifting it by the rear edge. To remove the fan, release the
retaining clips by pulling the back edge (1) of the fan upwards. Disconnect the cable
(2, detachable terminal). Install the new fan in reverse order.

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 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]).
