How to install Vertiv Liebert PSI5 UPS 1500VA 1350W 120VAC AVR Tower/Rack with Network Card

Installing the Vertiv Liebert PSI5 UPS is a straightforward process designed to minimize downtime and ensure optimal protection for your devices. Follow these practical steps to deploy the unit in a tower or rack configuration and enable full monitoring via the included network management card:

• Unpack and inspect: Carefully remove the PSI5 UPS from its packaging, verifying that all components—including the unit, mounting rails (for rack installation), and the RDU120 Network Management Card—are present and undamaged. Check for any shipping damage and retain the packaging for potential return or transport needs.
• Choose your orientation: Determine whether you will use the tower or rack-mount configuration. If rack-mounting, install the included rails and secure the UPS in the rack at a convenient height that allows for proper cable access and airflow. Ensure there is adequate clearance for ventilation and that the unit sits on a stable surface.
• Mount and cabling: Place the UPS in its designated space, then connect the input power cable to a properly grounded 120 VAC outlet. Avoid daisy-chaining power strips; provide a dedicated circuit if possible to minimize the risk of external disturbances affecting the UPS performance.
• Connect protected loads: Use high-quality, properly rated power cords to connect servers, switches, storage devices, and other critical equipment to the UPS’s output receptacles. Group protected devices based on priority and anticipated load to optimize battery runtime for essential systems during outages.
• Install network management and configuration: If not pre-installed, insert the RDU120 Network Management Card into the designated slot on the UPS or connect it per the included user guide. Connect the card to your network infrastructure and use Vertiv’s management software or a compatible browser to access the UPS status page. Configure SNMP, email alerts, and other notifications to stay informed about battery health, load, and input/output conditions.
• Initial startup and AVR calibration: Power on the UPS and allow for a short warm-up period. Confirm that the AVR is actively regulating voltage and that the UPS passes a basic self-test. If your environment experiences frequent voltage fluctuations, enable extended AVR settings to stabilize the output for connected devices.
• Battery and runtime checks: Run a battery test according to the user manual to verify capacity and performance. Review runtime estimates based on your actual load and plan maintenance windows or battery replacement intervals as needed to maintain reliability.
• Documentation and warranty: Register the product with Vertiv to access warranty information, support resources, and software updates. Keep the installation manual and card documentation readily accessible for future reference and troubleshooting.

Frequently asked questions

• Q: What does the PSI5 UPS protect, and what loads should I connect to it? A: The PSI5 is designed to protect critical IT loads such as servers, network switches, storage devices, and other sensitive electronics. It’s best to connect devices that require clean, stable power and device reliability. Prioritize essential equipment to maximize runtime during outages and consider staging less critical devices on separate outlets if needed.
• Q: Does the PSI5 support tower and rack installation? A: Yes. The Vertiv Liebert PSI5 is designed for flexible deployment, offering both tower and rack-mount configurations to suit your space and cable management preferences.
• Q: What management options are available with the RDU120 card? A: The RDU120 provides remote monitoring, alerts, and control through network interfaces. It supports standard management protocols and can integrate with Vertiv software as well as compatible third-party monitoring systems to help you track battery health, load, input/output voltage, and event history.
• Q: Is the PSI5 TA A compliant, and what does that mean for procurement? A: TA A compliance indicates the unit meets specific government procurement requirements, making it a viable option for government projects and enterprise deployments that require compliant power protection hardware.
• Q: How is the battery protected and how do I replace it? A: The PSI5 uses a sealed lead-acid battery system designed for reliability and ease of replacement. Replacement procedures are outlined in the user manual and should be performed by trained personnel per safety guidelines. Regular battery health checks and timely replacement help ensure reliable runtime during outages.
• Q: What is the expected runtime at typical loads? A: Runtime varies with load. At moderate loads near 50% of rated capacity, you can expect longer runtimes, while higher loads will shorten runtime. Use the management card’s monitoring data to estimate precise runtimes for your configuration and plan accordingly.
