How to Install Vertiv Liebert GXT3 UPS Replacement Battery Kit (GXT3-1MTBATKIT)

Before you begin, ensure you have the proper safety gear and follow all local regulations for handling batteries. Power down the UPS, unplug from outlets, and disconnect any connected equipment. Allow the unit to cool if it has been in service, and consult the Liebert GXT3 maintenance manual for model-specific guidance.

Step 1: Access the UPS battery compartment. Remove any protective covers and verify that you are working in a dry, well-ventilated area. Identify the existing battery modules and the wiring harness that connects them to the UPS interface.

Step 2: De-energize and disconnect the old battery modules. If there is residual voltage, isolate the batteries according to the manufacturer’s safety instructions and prepare for disposal or recycling in compliance with local regulations.

Step 3: Unpack the GXT3-1MTBATKIT. Inspect the battery modules, harnesses, and mounting hardware for any signs of shipping damage. Confirm that all components listed in the kit are present before proceeding with installation.

Step 4: Mount the new battery modules in the same layout as the original configuration. Use the provided mounting hardware to secure the modules to the UPS enclosure, ensuring clean cable management and proper ventilation around the battery area.

Step 5: Connect the pre-wired battery harness to the corresponding connectors on the new modules. Make sure each connector seats fully with a firm, locking engagement if applicable. Route the harness to avoid pinching, heat sources, or interference with moving parts.

Step 6: Reattach the harness to the UPS battery interface. Close the battery compartment, restore power, and power on the UPS. Observe the status indicators to confirm that the battery is detected, charged, and functioning properly. If your unit requires a battery health or runtime test, perform the test as outlined in the Liebert GXT3 maintenance guide.

Step 7: After the initial power-up, allow the batteries to begin a controlled recharge cycle. Do not load the UPS with critical equipment until the battery reaches a healthy state of charge, following the manufacturer’s recommendations for startup procedures.

Step 8: Document the replacement in your maintenance log, including date, technician, serial numbers, and any observed anomalies. Proper record-keeping supports warranty claims and future troubleshooting, and it helps ensure long-term reliability of your Liebert GXT3 system.

Tip: If you encounter any unusual fault codes or alarm indicators after installation, consult Vertiv support or the Liebert GXT3 maintenance documentation. Proper electrical isolation, grounding, and adherence to safety guidelines are essential for a successful battery kit replacement.
