Capacitors

The intermediate DC circuit of the drive contains several electrolytic capacitors.
Operating time, load, and surrounding air temperature have an effect on the life
of the capacitors. Capacitor life can be extended by decreasing the surrounding
air temperature.
Capacitor failure is usually followed by damage to the unit and an input cable fuse
failure, or a fault trip. If you think that any capacitors in the drive have failed,
contact ABB.

Reforming the capacitors

The capacitors must be reformed if the drive has not been powered (either in
storage or unused) for a year or more. The manufacturing date is on the type
designation label. For information on reforming the capacitors, refer to Capacitor
reforming instructions (3BFE64059629 [English]).

Control panel

Refer to ACS-AP-I, -S, -W and ACH-AP-H, -W Assistant control panels user's manual
(3AUA0000085685 [English]).
