Maintenance 155

Capacitors

The DC link 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, see Capacitor reforming instructions
(3BFE64059629 [English]) in the ABB Library (https://library.abb.com/en).

Control panel

See ACx-AP-x Assistant control panels user's manual (3AUA0000085685 [English]).

Drive LEDs

There is a green POWER and a red FAULT LED visible when the control panel is
removed. If a control panel is attached to the drive, switch to remote control otherwise
a fault will be generated, and then remove the panel to be able to see the LEDs. See
the firmware manual on how to switch to remote control.
The table below describes the drive LED indications.
