13. Install the new module in reverse order.

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. 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 be 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]).
