How to install Vertiv Liebert TAA 72V External Battery Cabinet

Preparing for installation starts with confirming compatibility and ensuring a clean, ambient environment for the battery cabinet. Verify that your Liebert GXT5 VRLA UPS is configured to accept an external 72V battery cabinet and that there is sufficient space for the enclosure near the UPS with appropriate clearance for airflow and access.

1. Power down and isolate: Before any connections, safely shut down connected loads and switch off the Liebert GXT5 system according to the manufacturer’s instructions. Lockout/tagout procedures should be followed if applicable to your site.

2. Position and secure the cabinet: Move the 72V external battery cabinet into its designated location near the Liebert GXT5. Ensure the surface is level and stable, and that there is adequate ventilation to prevent overheating. If floor mounting is used, secure the cabinet according to local electrical and building codes.

3. Connect interconnection cabling: Use the approved interconnection cable provided or specified by Vertiv to link the Liebert GXT5 UPS to the external battery cabinet. Follow the exact wiring sequence and polarity as described in the installation guide to ensure proper communication and safe operation. Confirm all connections are snug and secure.

4. Grounding and safety checks: Verify proper grounding for both the UPS and the external cabinet. Inspect the enclosure for any visible damage, loose components, or signs of wear. Ensure that cabinet doors are properly closed and locked to protect the batteries and prevent unauthorized access.

5. System configuration: Power on the Liebert GXT5 and navigate to the battery configuration settings. Enable external battery cabinet support if required by firmware, and run any built-in self-tests to verify successful recognition of the 72V cabinet. If firmware updates are recommended, apply them before full-load testing.

6. Initial load testing: With the external cabinet connected, perform a controlled load test to confirm that the Liebert GXT5 can gracefully transition to external battery power and that runtime extension functions as expected. Monitor system temperatures, voltage levels, and battery health indicators during the test.

7. Documentation and maintenance planning: Record the installation details, including cabinet model, serial numbers, firmware versions, and test results. Establish a maintenance plan that includes regular battery health checks, voltage checks, and periodic replacements based on manufacturer recommendations and site conditions.

By following these steps, you ensure a safe, compliant, and effective deployment of the Vertiv Liebert TAA 72V External Battery Cabinet with your Liebert GXT5 VRLA UPS. The result is a resilient, scalable power solution that protects critical loads and maintains service continuity across a range of operating environments.
