ABB Water Drive ACQ580-01-039A-4

Warning: This procedure requires trained personnel with PPE!

Capacitors: The intermediate DC circuit 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.

Check capacitor reforming for spare modules and spare capacitors

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.

Enter the manufacturing date of the capacitor

Has the drive been powered in the last year?

Electrical safety in installation, start-up and maintenance

WARNING! Obey these instructions. If you ignore them, injury or death, or damage to the equipment can occur.

If you are not a qualified electrical professional, do not do installation or maintenance work.

Do these steps before you begin any installation or maintenance work.

Clearly identify the work location and equipment.

Disconnect all possible voltage sources. Make sure that re-connection is not possible. Lock out and tag out.

Protect any other energized parts in the work location against contact.

Take special precautions when close to bare conductors.

Warning: This procedure requires trained personnel with PPE!

The mission time of functional safety components is 20 years.

The expiry of mission time terminates the certification and SIL/PL classification of the safety function.

Note: Renewal of components is economical only with larger drives that have replaceable circuit boards and other components such as relays.

Check if the components have been renewed earlier

The remaining mission time of the whole circuit is determined by its oldest component.

Enter the age of the oldest component in the circuit

Parameter 05.04 Fan on-time counter indicates the running time of the cooling fan. Reset the counter after a fan replacement. See the firmware manual.

In a speed-controlled fan, the speed of the fan matches the cooling needs. This increases the life span of the fan.

Main fans are speed controlled. When the drive is stopped, the main fan runs at low speed until the drive cools down. IP21 (UL Type 1) frames R5..R9 and all IP55 (UL Type 12) frames have auxiliary fans that are not speed controlled and run all the time when the control unit is powered.

Replacement fans are available from the manufacturer. Do not use other than specified spare parts.

Electrical safety in installation, start-up and maintenance

These electrical safety precautions are for all personnel who do work on the drive, motor cable or motor.
