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. 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 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 ACS 600/800
Capacitor Reforming Guide (code: 64059629).
LEDs
This table describes LEDs of the drive.
* The LEDs are not visible
Where LED When the LED is lit
RMIO board * Red Drive in fault state
Green The power supply on the board is OK.
Control panel mounting platform Red Drive in fault state
Green The main +24 V power supply for the control panel and the
RMIO board is OK.
