104 Maintenance

Replacing the LCL filter module

Replace the LCL filter module in the same way as the drive module.

Capacitors

The DC circuit of the power modules of the drive contain several electrolytic capacitors.
Their lifespan depends on the operating time of the drive, loading and ambient temperature.
Capacitor life can be prolonged by lowering the ambient 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 Converter module capacitor reforming
instructions (3BFE64059629 [English]) in the ABB Library (https://library.abb.com/en).

Control panel

For detailed information on the control panel, see ACx-AP-x assistant control panels user's
manual (3AUA0000085685 [English]).
￭

Cleaning the control panel

Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could scratch
the display window.
