Maintain a defined Power Protection coverage term for Vertiv PSI Lithium 3K UPS installations with ZPSIL-PC-3K-04. The service-plan designation applies to the 3K UPS capacity tier and spans years 1 through 4. It is intended for environments using PSI Lithium systems where the coverage term must align with the installed UPS platform and capacity class. The 3K designation is an important selection point. UPS service coverage must correspond to the protected system’s capacity tier rather than only its product family, particularly where multiple UPS sizes are deployed in the same server room, network closet, branch site, or equipment enclosure. This SKU is associated with the PSI Lithium 3K configuration, helping keep the coverage selection aligned with that UPS class. The years 1–4 term distinguishes this Power Protection option from coverage selections with a different duration or lifecycle position. Use it when the required service period is the first four years of operation for the applicable PSI Lithium 3K system. Verify the installed UPS model, capacity tier, and required coverage dates before assigning the service plan to an existing power-protection deployment.
