ABB Water Drive ACQ580-01-033A-4

Warning: This procedure requires trained personnel with PPE!

Has the drive been powered in the last year?

If the drive has not been powered in the last year, the capacitors must be reformed.

Check capacitor reforming for spare modules and spare capacitors

Report any suspected capacitor failures

Sign off on the capacitor check

Check quality of supply voltage

Inspect dustiness, corrosion or temperature

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

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.;

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

Before you begin any installation or maintenance work, follow these steps:

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.

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

Install temporary grounding as required by the local regulations.

Ask for a permit to work from the person in control of the electrical installation work.
