ACH580-01 Installation
Capacitors
The drive intermediate DC circuit employs 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 drive and an input cable fuse
failure, or a fault trip. Contact the manufacturer if capacitor failure is suspected.
Replacements are available from the manufacturer. Do not use other than specified
spare parts.
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. See label on page
7 for how to find out the
manufacturing date from the serial number.
For information on reforming the capacitors, see Converter module capacitor
reforming instructions (3BFE64059629 [English]), available on the Internet (go to
http://www.abb.com and enter the document code in the Search field).
Control panel
Cleaning
Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could
scratch the display window.
Battery
A battery is used in all control panels to keep the clock operating in memory during
power interruptions.
The expected life for the battery is greater than ten years. To remove the battery, use
a coin to rotate the battery holder on the back of the control panel. Replace the
battery with type CR2032.
Note: The battery is NOT required for any control panel or drive function, except the
real-time clock.
