how to install Eaton 9PX 3000VA 208V Online UPS

Install this UPS quickly and safely with a few straightforward steps. Begin by selecting a suitable mounting location that allows for effortless access, adequate ventilation, and clearance for ventilation, service, and cable management. The 3U rack/tower design lets you mount it in a standard IT rack or place it on a stable surface as a tower, depending on your space constraints.

• Power down all equipment you plan to protect and mount the UPS in its chosen position, ensuring the site remains free of moisture and excessive heat. Use proper rack rails or base supports to secure the unit.
• Connect the facility power to the UPS input using the L6-30P connector. Verify that the input power is stable and within the UPS’s intended voltage range to prevent nuisance transfer events.
• Attach protected devices to the respective outlets: place critical servers and storage on the 2 x L6-30R outlets and less critical networking gear on the 2 x L6-20R outlets. Group devices by importance to optimize shutdown sequencing in an outage.
• Install the Cybersecure Network Card if not pre-installed and connect the UPS to your network. Use Eaton Power Management software or your preferred management tool to configure alerts, shutdown policies, and firmware updates. Enable secure access controls to maximize cybersecurity.
• Power on the UPS, run the built-in self-test, and verify battery health and runtime estimates under typical load. Configure automatic shutdown settings for connected equipment and schedule periodic maintenance checks for battery packs and firmware.
