4.3.3Limited Life Components

Your Liebert UPS has a design life well in excess of 10 years. Well-maintained units can continue to provide economic benefits for 20 years or more. Long-life components are used in your UPS wherever practical and cost-effective. However, due to current component material and manufacturing technol- ogy limitations, a few components in your Liebert UPS will wear out and require replacement in less than 10 years.

The following limited-life components are utilized in your UPS system. To prevent a wear-out failure of one of these components affecting your critical load operations, Liebert recommends these compo- nents be periodically inspected and replaced before their expected wear-out life. Individual users may have site-specific requirements that differ from these typical life expectations.

Power capacitors are considered “failed” when their measured capacitance is -5% below their name- plate rating. Typically, storage batteries are “worn out” when their full-load reserve time is -20% below rated. Site-specific battery plants may have different end-of-life requirements. Fans and blow- ers typically will stop rotating or rotate slower than expected.

In most cases, replacement components must exactly match the original component specifications and are not readily available from third-party component distributors. For assistance with your specific component specifications, replacement component selection and sourcing, call 1-800-LIEBERT.

For customers using Liebert Global Services (LGS) Preventive Maintenance Services, periodic inspec- tion of these components is part of this service, as well as recommending replacement intervals to cus- tomers to avoid unanticipated interruptions in critical load operations.
