How to install Vertiv Liebert PSI5 Lithium-Ion TAA UPS

• Choose an installation location with adequate ventilation, stable support, and access for maintenance. Decide between rack mounting or placing the unit in a tower configuration based on your space and cabling layout.
• Mount the UPS in a compatible rack or secure it on a stable surface. Ensure there is sufficient clearance around the unit for air flow and easy access to input/output connections.
• Connect the UPS to a properly grounded 120V outlet that matches the unit’s specifications. Verify the receptacles and cable ratings align with the load you intend to protect.
• Connect protected devices to the UPS outlets, distributing the load so it does not exceed the 1920W rating. Spread critical servers, storage, and networking gear across outlets as needed to balance power across the system.
• Power on the UPS and run a built-in self-test to verify正常 operation and battery health. If available, configure any local or remote monitoring options to track runtime, input/output voltage, and overall system health for proactive maintenance.
