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

■
Cleaning the control panel
Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could scratch
the display window.
■
Replacing the battery
The instructions below describe how to replace the battery that powers the real-time clock
of the control panel.
1. Turn the lid on the back of the control panel counter-clockwise until the lid opens.
2. Remove the battery gently.
3. Replace the battery with a new CR2032 battery. The battery holder has grip nails.
First slide the battery and then press on the other side. The battery will snap in.
4. Make sure that the battery polarity shows positive on the upside.
5. Put the lid back and tighten it by turning it clockwise.
6. Dispose of the old battery according to local disposal rules or applicable laws.
