ABB Drive Module ACS850-04

- Control Panel Battery Replacement. The battery is housed on the rear of the control panel. Replace with a new CR 2032 battery.;

- Checking the Condition of Fiber Optic Cables. - See the fault logger. If PPCC LINK faults have recurred, change the fiber optic cables.;

- Change cooling fan every 3 years if the ambient temperature is higher than 40°C (104°F).; Otherwise, every 6 years.

- The lifespan of the cooling fan of the drive module is about 50,000 hours. The actual lifespan depends on the running time of the fan, ambient temperature, and dust concentration. See the appropriate Firmware Manual for the actual signal which indicates the running time of the cooling fan. For resetting the running time signal after a fan replacement, please contact ABB. Replacement fans are available from ABB. Do not use other than ABB specified spare parts.;

- Every 6 to 12 Months (depending on the dustiness of the environment) Checking the Cleanliness of the Cabinet and the Surroundings.;

- Change capacitor every 6 years if the ambient temperature is higher than 40°C (104°F) or if the drive is subjected to cyclic heavy load or continuous nominal load.; Otherwise, every 9 years.

- The drive intermediate circuit employs several electrolytic capacitors. Their lifespan is at least 90,000 hours depending on the operating time of the drive, loading, and ambient temperature

Capacitor life can be prolonged by lowering the ambient temperature. It is not possible to predict a capacitor failure. 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.;
