ABB Water Drive ACQ580-01-02A7-4

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

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.

Warning: This procedure requires trained personnel with PPE!

The mission time of functional safety components is 20 years.

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

Note: Renewal of components is economical only with larger drives that have replaceable circuit boards and other components such as relays.

The remaining mission time of the whole circuit is however determined by its oldest component.

Enter the age of the oldest component in the circuit

Did the safety function pass the post-renewal test?

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.
