How to Install Vertiv Liebert TAA 48V External Battery Cabinet

Preparing for installation starts with confirming compatibility and planning placement. Ensure the Liebert GXT5 UPS is powered down and that you have the appropriate battery harness connections and monitoring interfaces. Identify a location that provides adequate ventilation, defined clearance for service access, and proximity to the UPS to minimize cabling length and impedance. Review the cabinet labeling and wiring diagrams before beginning to reduce the risk of errors during connection.

Step 1: Position the external cabinet in a suitable location. Align it near the Liebert GXT5 unit to shorten cable runs and facilitate monitoring. Check clearances for safe operation, maintenance access, and airflow. If mounting is required, follow your facility’s guidelines for floor-standing or rack-adjacent installation and secure the cabinet according to the manufacturer’s recommendations.

Step 2: Connect power and grounding. Attach the cabinet’s grounding conductor to the facility ground, then connect the 48V DC battery output to the appropriate terminals on the Liebert GXT5 battery harness. Use the provided torque specifications and proper connectors to ensure a secure, low-resistance connection. Double-check polarity and verify that all connections are snug before applying power.

Step 3: Integrate monitoring and communication. Link the cabinet to the Liebert GXT5 monitoring ecosystem as directed in the installation guide. This enables battery status data, temperature readings, and alarms to flow into the UPS management console, providing a unified view of runtime, health, and potential fault conditions across the power system.

Step 4: Perform a system initialization. Power up the Liebert GXT5 UPS and the external cabinet in sequence, allowing the battery management system to initialize. Initiate a controlled battery test or runtime simulation as recommended by the manufacturer. Observe the indicators and logs for any abnormal conditions, and address alarms promptly if they appear.

Step 5: Configure runtime targets and alarms. Set target runtimes based on critical load profiles and business requirements. Establish alarm thresholds for temperature, voltage, and impedance, and enable alert routing to facilities staff or a monitoring service. Document the configuration for future maintenance and audits.

Step 6: Validate performance and safety. Run a full-load test if approved by your safety policies. Confirm that the UPS and external cabinet deliver the expected backup duration under simulated outages. Verify that cooling, ventilation, and accessibility remain within safe operating parameters. Once validated, update your maintenance calendar with periodic battery checks and preventive service windows.

Note: Installation details may vary by model revision and facility environment. Always consult the official installation guide and datasheets for exact wiring schemes, torque specifications, and safety instructions. If you are uncertain about any step, contact Vertiv support or a qualified electrician to ensure proper, code-compliant installation.
