Replacement (R4, R5)

The fan is located on the lower right-hand side of the unit (R4) or on the right-hand
side of the control panel (R5). Lift the fan out and disconnect the cable. Install the fan
in reverse order.

Replacement (R6)

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. Their lifespan
is from 45 000 to 90 000 hours depending 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 ACS600/800
Capacitor Reforming Guide [3AFE64059629 (English)].
