ABB Water Drive ACQ580-01-02A7-4

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.

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 a qualified electrical professional. Do not attempt if you are not qualified.

Identify the work location and equipment.

All possible voltage sources disconnected and re-connection locked out and tagged out?

All dangerous external voltages from the control circuits disconnected?

Waited 5 minutes to let the intermediate circuit capacitors discharge?

All other energized parts in the work location protected against contact?

Special precautions taken when close to bare conductors?

Voltage between the drive input power terminals (L1, L2, L3) and the grounding (PE) busbar is zero?

Warning: This procedure requires a qualified electrical professional. Do not attempt if you are not qualified.

Before starting, ensure all possible voltage sources are disconnected and the work location is clearly identified.

Voltage sources disconnected and work location identified?

Wait for 5 minutes to let the intermediate circuit capacitors discharge before you continue.

Measure that the installation is de-energized using a quality voltage tester.

Install temporary grounding as required by the local regulations.

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.

Has the drive been powered in the last year?

If the drive has not been powered for a year or more, the capacitors must be reformed.

Enter the surrounding air temperature

Check capacitor reforming for spare modules and spare capacitors

Report any signs of capacitor failure
