Lenovo’s RT8kVA/RT11kVA product guide identifies the RT8kVA 6U Rack or Tower UPS (200-240VAC) as part number 55948KX. It is distinct from the 380-415VAC three-phase-input variant.
Match support resources to the voltage and model shown on your UPS. For power-management software or a network-management component, check its own hardware, operating-system and version requirements. The UPS model name alone does not establish that a Windows 10 or Windows 11 package applies.
