How to Install PSI5 Replacement Internal Battery Kit

Installing the PSI5 replacement battery kit is designed to be straightforward for technicians familiar with Liebert UPS systems. The steps below outline the typical process to replace the internal battery kit while minimizing downtime and preserving load protection during the upgrade.

Step 1: Power down and prepare the system. Begin by shutting down all connected equipment and safely powering off the PSI5-1500RT120 UPS according to the manufacturer’s guidelines. Unplug the UPS from the wall outlet to eliminate any residual energy in the system.

Step 2: Access the battery compartment. Remove the service access panel or enclosure cover following the Liebert PSI5 user manual. Ensure you are working in a dry, clean environment and that the area is free from potential hazards.

Step 3: Disconnect the existing battery connections. Carefully release the battery connectors and take note of the wiring arrangement to ensure correct reattachment of the replacement kit. Use appropriate insulated tools and avoid pinching cables during removal.

Step 4: Remove the old battery module and install the new kit. Slide the PSI5-1500BATKITTAA into the internal bay, aligning mounting points and connectors precisely with the UPS docking points. Reconnect the battery harness, ensuring each connector seats firmly and that no wires are loose or stressed.

Step 5: Re-seal and restore power. Replace the battery compartment cover and secure it with the appropriate fasteners. Restore power by reconnecting the UPS to the wall outlet, and ensure all indicators return to normal states on the front panel.

Step 6: Verify operation and run a self-test. Once powered, run a self-test or diagnostics through the UPS interface to confirm healthy battery status, expected runtime, and proper charging behavior. Monitor for any warning or fault indicators and address them according to the user manual.

Step 7: Resume normal operations. After validating the battery kit’s performance, re-enroll the UPS in its normal monitoring workflow. If you use network management software, check that the PSI5-1500BATKITTAA is being reported correctly and that runtime estimates reflect the refreshed battery capacity.

Additional notes for installation: Always follow proper lockout/tagout procedures and consult the official Liebert PSI5 manuals for any model-specific instructions. If you are unsure about handling battery components or accessing internal hardware, contact a qualified technician or Vertiv support for installation assistance. Proper handling and disposal of the old battery kit in accordance with local regulations is recommended to ensure environmental safety.
