How to install PSI5-3000BATKITTAA

Installing the PSI5-3000BATKITTAA is a straightforward process designed to minimize downtime and maintain protective uptime for your critical systems. Follow these general steps in accordance with your facility’s safety procedures and your Liebert PSI5 UPS manual for hot-swappable battery replacement.

1. Prepare and power down as recommended: If your UPS supports hot-swappable battery replacement, you may perform the swap with the system running while the protected load remains online. If your operating procedure requires a controlled shutdown, power down the UPS and disconnect the load according to your organizational policy.
2. Access the battery compartment: Locate the battery compartment on the PSI5-3000RT120. Use the appropriate latch or panel removal method to open the access door, exposing the existing internal battery pack.
3. Disconnect the old battery kit: Carefully detach the connectors and any locking fasteners holding the old battery assembly in place. Note the orientation and connector types to ensure proper reattachment of the new kit.
4. Install the PSI5-3000BATKITTAA: Align the new battery kit with the connector interfaces and the mounting points inside the UPS. Reconnect all cables securely, paying attention to correct polarity and connector seating to prevent arcing or poor contact.
5. Reconnect, reseal, and test: Close the battery compartment, secure the panel, and restore power to the UPS if you powered down. Initiate a self-test or battery calibration per the Liebert PSI5 guidance to confirm battery health and startup readiness. Monitor the status indicators to verify normal operation and runtime restoration.

Practical tips for installers and administrators:

• Handle the battery kit with care; avoid short circuits and avoid opening or puncturing the VRLA cells.
• Ensure adequate ventilation around the UPS during installation to maintain safe operating temperatures.
• Consult the Liebert PSI5 documentation for any model-specific hot-swap requirements, including sequence and safety precautions.
• Keep record of the replacement date for maintenance tracking and future battery lifecycle planning.
• Dispose of old battery packs in accordance with local regulations and recycling programs.
