ABB Water Drive ACQ580-01-026A-4

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

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 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?

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.

The mission time of functional safety components is 20 years which equals the time during which failure rates of electronic components remain constant.

This applies to the components of the standard Safe torque off circuit as well as any modules, relays and, typically, any other components that are part of functional safety circuits.

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

• Renewal of the whole drive and all optional functional safety module(s) and components.

• Renewal of the components in the safety function circuit. In practice, this is economical only with larger drives that have replaceable circuit boards and other components such as relays.

Note that some of the components may already have been renewed earlier, restarting their mission time. The remaining mission time of the whole circuit is however determined by its oldest component.;

Waited 5 minutes after disconnecting power from the drive to let the intermediate circuit capacitors discharge?

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

Installed temporary grounding as required by the local regulations?

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

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.
