Capacitors

The drive intermediate circuit contains 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. Contact ABB if capacitor failure is suspected. Replacements are available
from ABB. Do not use other than ABB specified spare parts.

Reforming the capacitors


The capacitors must re reformed if the drive has been stored 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]).

Control panel

Replacing the control panel battery


1. Turn the lid on the back of the panel counter-clockwise until the lid opens.
2. Replace the battery with a new CR2032 battery.
3. Put the lid back and tighten it by turning it clockwise.
4. Dispose of the old battery according to local disposal rules or applicable laws.
