ABB Water Drive ACQ580-01-169A-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.

Check quality of supply voltage

Inspect dustiness, corrosion or temperature

Inspect IP66 (UL Type 4X) frames R1..R3: Drive cover and gasket assembly

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

Clearly identified the work location and equipment?

Disconnected all possible voltage sources and ensured re-connection is not possible?

Protected any other energized parts in the work location against contact?

Taken special precautions when close to bare conductors?

Measured that the installation is de-energized using a quality voltage tester?

Installed temporary grounding as required by the local regulations?

Obtained a permit to work from the person in control of the electrical installation work?

Warning: This procedure requires trained personnel with PPE!

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.

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.

Check capacitor reforming for spare modules and spare capacitors

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

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

Voltage between the drive output terminals (T1/U, T2/V, T3/W) and the grounding (PE) busbar

Voltage between the drive DC terminals (UDC+ and UDC-) and the grounding (PE) terminal
