ABB Water Drive ACQ580-01-046A-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.

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

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

Replacing the auxiliary cooling fan, IP55 (UL Type 12) frames R1...R2

Warning: This procedure requires a qualified electrical professional. Failure to comply can result in injury, death, or damage to the equipment.

Before starting, 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 after disconnecting power from the drive to let the intermediate circuit capacitors discharge?

All 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

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

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

Before starting, disconnect all possible voltage sources and ensure the installation is de-energized.

Is the work location and equipment clearly identified?

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

Are all dangerous external voltages from the control circuits disconnected?

Have you waited 5 minutes after disconnecting power from the drive to let the intermediate circuit capacitors discharge?

Are all other energized parts in the work location protected against contact?

Have you measured that the installation is de-energized using a quality voltage tester?

Have you installed temporary grounding as required by the local regulations?
