Designed for reliability, performance, and ease of management, this unit helps IT teams maintain uptime, protect data, and streamline operations in dynamic environments.

• Reliable online double-conversion protection: The 9PX continuously converts incoming AC to DC and back to a pure, regulated AC output. This topology isolates sensitive equipment from input disturbances, provides clean, distortion-free power, and safeguards against outages, surges, and line noise. With this level of protection, you can minimize unexpected reboots, data corruption, and hardware wear, keeping critical workloads running smoothly during power events.
• High-capacity 3 kVA / 3 kW at 208V for IT resilience: This UPS delivers robust performance for servers, virtualization hosts, storage arrays, and network devices. Its 208V capability is ideal for data centers, remote offices, and edge sites that rely on a precise power supply. The reserve capacity supports startup surges, peak loads, and growth, providing headroom for expansion without compromising uptime.
• Extensive outlet configuration for flexible power distribution: The unit provides 18 x NEMA 5-20R outlets, plus 2 x NEMA L6-20R and 1 x NEMA L6-30R outlets. This diverse mix simplifies cable management, reduces the need for adapters, and enables clean separation of critical equipment from nonessential peripherals. The arrangement is designed to support rack-mounted servers, switches, storage devices, and ancillary IT gear in one compact enclosure.
• Cybersecure Network Card and intelligent management: Included Cybersecure Network Card enables secure remote monitoring, management, and controlled shutdowns. Combined with USB and RS-232 connectivity, it supports standard management protocols (SNMP, HTTP/HTTPS, and vendor software) to keep administrators informed, proactively alert on faults, and streamline orderly power-down procedures during outages.
• Extended Run capability and flexible form factor: The 9PX supports extended runtime through external battery packs, allowing longer outages to be survived without service interruption for critical workloads. Its 6U rack/tower form factor provides flexible installation in standard 19-inch racks or as a standalone tower, making it suitable for data centers, edge facilities, and hybrid cloud deployments that require adaptable infrastructure.

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

• Plan placement: Select a cool, ventilated area with unobstructed access for cable routing, routine maintenance, and battery replacement. Ensure a dedicated 30 A circuit (L6-30P) for input power in 208 V environments, and verify grounding per local electrical codes.
• Choose configuration: Decide between rack-mount or tower deployment. If rack-mounting, allocate 6U of space in a standard 19-inch rack and secure the unit with the supplied hardware; for towers, place on a solid, level surface with adequate clearance for airflow.
• Connect the loads: Arrange critical IT devices (servers, switches, storage, and network gear) on the 5-20R outlets, reserving L6-series outlets for higher-current devices as needed. Distribute loads to balance current across outlets and avoid overloading any single receptacle.
• Connect the input power: Plug the L6-30P connector into the dedicated 208 V circuit. Ensure correct wiring, grounding, and adherence to electrical codes. Use appropriate cables and clamps to secure cables and prevent strain.
• Enable management and monitoring: Install the Cybersecure Network Card if not pre-installed, connect the UPS to your network, and install Eaton Power Management software on servers. Configure alerting, shutdown policies, and scheduled battery checks to automate safe power-off sequences during outages.
• Initial power-up and testing: Power on the UPS, run a built-in self-test, and verify that connected equipment gracefully shuts down when commanded during a simulated outage. Confirm network alerts, USB/serial communications, and software integration are functioning as expected.
• Plan for extended runtime: If your environment requires longer outages, evaluate external battery packs or Extended Run options and plan their installation and commissioning according to the manufacturer guidelines.
• Maintenance and health checks: Establish a regular maintenance routine, including battery health testing, firmware updates, and periodic reviews of runtime requirements to ensure ongoing reliability.
