How to install Vertiv Liebert GXT5 External Battery Cabinet

Before you begin, verify that the Liebert GXT5 UPS is powered down and that all safety procedures for handling electrical equipment are followed. Ensure you have the appropriate mounting rails, cables, and documentation from Vertiv for your specific model configuration. The steps below describe a typical installation workflow for adding the external battery cabinet to a compatible Liebert GXT5 system.

Step 1: Prepare the rack and cabinet

Confirm there is a clear 2U space in your 19-inch rack for the external battery cabinet and that adjacent components will not obstruct airflow. Keep the area around the cabinet well-ventilated and free of dust or debris that could affect airflow or battery health. Inspect the cabinet and all hardware to ensure there are no transport-related damages from shipping.

Step 2: Mount the cabinet in the rack

Slide the external battery cabinet into the designated 2U rack space and secure it to the rack rails using the supplied mounting hardware. Ensure the cabinet is level and firmly fastened to prevent vibrations or movement during operation. Maintain proper clearance for cable connections and service access.

Step 3: Connect the cabinet to the Liebert GXT5 UPS

Connect the external battery cabinet to the Liebert GXT5 UPS using the manufacturer-recommended interconnect cables. Follow the wiring diagram accompanying your unit to ensure correct polarity and secure terminations. Do not power the UPS until all connections are verified and tightened as per the manual.

Step 4: Configure and verify

Power on the Liebert GXT5 UPS and allow the system to initialize. Use the back-panel indicators or the USB/serial management interface to confirm the external cabinet is recognized and reporting its status correctly. Run a basic battery health check or a battery test to validate proper operation and conditioning cycles.

Step 5: Test the integrated system under load

With load connected to the UPS, perform a controlled outage test to confirm the extended runtime provided by the external cabinet. Observe the UPS behavior, alarm states, and runtime calculations to ensure the system meets your recovery objectives. Document the test results and adjust maintenance schedules as needed to maintain peak performance.

Maintenance notes: Regularly inspect the cabinet’s venting, battery modules, and interconnects. Schedule battery health checks in accordance with your organization’s maintenance policy to ensure longevity and reliability. If you notice any unusual heat, swelling, or warning indicators, contact Vertiv support for guidance and potential battery module replacement.
