• High-capacity power protection: The PSI5 delivers up to 1920VA / 1920W of backup power to keep essential devices running during outages or brownouts, enabling safe shutdowns and continued operation of critical equipment such as servers, network gear, and audiovisual systems. With ample capacity to support multiple devices, you can maintain productivity and prevent data loss even when the main power is unstable.
• Line-interactive AVR technology: Automatic Voltage Regulation continuously corrects under- and over-voltage conditions without drawing from the battery. This intelligent conditioning minimizes battery wear while delivering clean, stable sine-like power to connected equipment, reducing the risk of damage from fluctuating mains voltage and extending the life of your UPS battery.
• TAA-compliant for federal and commercial procurement: The PSI5 is designed to meet Trade Agreements Act requirements, making it a dependable choice for government facilities, educational institutions, and enterprises that require compliant power protection solutions. This compliance supports streamlined purchasing and procurement processes without compromising performance.
• Flexible mounting for tower or rack environments: The Vertiv Liebert PSI5 is engineered for versatile deployment, offering both tower and rack-mount options. Its compact footprint allows discreet placement under desks, inside equipment closets, or in small data centers, while its thermal and acoustic design keeps operating noise to a minimum in noise-sensitive environments.
• Comprehensive protection and easy management: Beyond backup power, the PSI5 provides surge suppression and robust protection for sensitive electronics. The system is designed for straightforward installation, intuitive setup, and reliable operation, helping to minimize downtime, simplify maintenance, and safeguard data integrity across classrooms, offices, and home office networks.

How to install Vertiv Liebert PSI5 UPS

• Plan the placement: Choose a stable, ventilated location near the devices you want to protect. If using a rack, ensure adequate clearance for airflow and access to outlets and any management ports. If used as a tower, place it on a flat surface away from direct heat sources and at a height that minimizes risk of tipping.
• Mounting configuration: Decide between tower or rack-mount orientation. For rack installation, follow the included mounting rails and hardware to secure the unit in the rack chassis. Ensure the UPS is level and stable to prevent vibration and noise during operation.
• Connect a grounded input power source: Plug the PSI5 into a properly grounded 120V circuit. It is important to use a dedicated circuit if possible to minimize electrical noise and maximize runtime reliability during outages.
• Attach protected equipment: Connect your critical devices to the UPS’s protected outlets. Leave nonessential devices on separate power sources if you require additional surge protection or load distribution.
• Power, test, and configure: Power on the UPS and perform an initial health check. If available, install and configure any included management software for graceful shutdowns, event logging, and alert notifications. Run a basic load test to verify proper operation and observe that the AVR function maintains stable voltage under simulated brownouts or surges.
• Maintenance reminders: Regularly inspect the battery, perform self-tests, and monitor software alerts. When the battery reaches end-of-life, replace it according to the manufacturer’s guidance to ensure continued protection and runtime performance.
