How to install Eaton 9SX 3000VA 208V UPS

• Choose a cool, dry, and well-ventilated location for the UPS—away from direct heat sources and moisture—with adequate clearance for airflow and maintenance access.
• Place the unit in a stable position. If you plan to convert to a rack-mount setup, follow the manufacturer’s guidelines to install the necessary mounting hardware and adapters.
• Connect the UPS to a dedicated 208V power circuit using the appropriate input cable. Ensure the circuit can handle the load in the event of a brief surge or outage.
• Connect critical loads to the NEMA 6-20R and L6 outlets as needed based on your protection plan. Reserve non-critical devices for secondary outlets to optimize runtime where possible.
• Install the battery(s) and verify battery status. If you are adding external battery modules for Extended Run, ensure they are properly connected and configured according to the user manual.
• Attach the optional Cybersecure Network Card if you require secure remote management. Connect the UPS to your network and configure it using Eaton’s management software or compatible tools for monitoring, alerts, and automated shutdowns.
• Perform a self-test from the front panel or via software to verify normal operation and confirm that outlets, alarms, and communication interfaces function correctly.
• Document the setup, including circuit ratings, outlet assignments, and network configuration. Regularly monitor using the included software to stay ahead of potential issues and to optimize runtime based on actual load patterns.
