Maintenance

3.2Liebert Services

Startup, UPS maintenance, battery maintenance and training programs are available for the Liebert NXL UPS through your Liebert sales representative.

3.2.1Professional Startup

UPS Startup—Liebert’s Customer Engineers perform a thorough non-powered inspection of the units and will then conduct a complete electrical checkout. The battery installation is also inspected and placed on an initialization charge to ensure cell equalization. Customer Operation training will be conducted during battery charge time.

Load bank testing and full site acceptance testing are additional services that can be performed dur- ing a UPS startup. One preventive maintenance service call can be added to the initial UPS startup agreement.

Battery Installation/Startup—When purchased with a UPS Start-Up, this Agreement provides consistent, professional service for your entire UPS system. This one-source approach avoids conflicts that may occur during a multisource installation. Note that Liebert requires a mandatory installation inspection for all batteries not installed by Liebert Customer Engineers.

Battery IEEE Certification Inspection - The Battery Specialist will perform a detailed inspection of the entire battery system to ensure it meets current IEEE standards.

Maintenance Agreements: The Signature Program

UPS Service Agreements—Liebert Services (LGS) has a variety of available maintenance agree- ments, depending on specific site needs. Choose the level of support appropriate for each installation.

Mission-critical sites can have the standard parts-and-labor, around-the-clock coverage for their UPS, with or without scheduled preventive maintenance visits. Other sites can benefit from a variety of money-saving options.

Liebert recommends two preventive maintenance visits per year for the UPS. The first can be con- ducted with the UPS operational and includes an infrared scan of key UPS components.

The annual visit will require taking the UPS off-line for a thorough non-powered inspection.

These visits are in addition to the general housekeeping tasks (changing air filters, etc.) that can be performed by customer personnel.

Battery Service Agreements—The same flexible Signature Program can also be applied to con- tracts for battery maintenance. Again, the coverage needed will depend on the type of battery pur- chased and the degree of support required from Liebert Services.

Training

Customer training courses include the proper operation of the system, emergency procedures, preven- tive maintenance and some corrective maintenance.

Warranties

Contact Liebert Services if you have any questions regarding the warranty on your Liebert NXL UPS or the batteries.
