How to Install Eaton 9PXM UPS

• Prepare site and rack space. Verify a dedicated 208–240 VAC three-phase supply and ensure the installation area has adequate ventilation and clearance for maintenance access. Confirm you have 21U of rack space and the appropriate mounting rails for a standard 19-inch rack.
• Unpack and inspect. Carefully unbox the UPS and any modular power or battery modules. Inspect for transit damage and verify all components listed in the packing list before proceeding.
• Install in the rack. Mount the UPS unit and place it securely on the rack rails. If you are adding modular power modules, install them per the manufacturer’s guidelines and connect hot-swappable modules only when power is de-energized or as directed by the manual.
• Connect input and output. Route hardwired input cables from the building distribution to the UPS input terminals. Connect protected loads to the UPS output terminals, following local electrical codes and conductor sizing requirements. Use appropriate strain relief and enclosure provisions as required.
• Install and configure the network card. Insert the cybersecure network card if not preinstalled. Connect the UPS management interface to your network and assign a static IP or configure DHCP as preferred. Update firmware to the latest release and enable secure access controls.
• Commission and test. Power up the system and perform a self-test as recommended by Eaton. Verify successful communication with the network card, confirm load transfer performance, and check for any fault indicators on the unit display or management console.
• Document and monitor. Record serial numbers, installation dates, and network settings. Set up alert thresholds and monitoring through your preferred DCIM or SNMP management tool to ensure ongoing visibility into UPS health and runtime.

Frequently asked questions

• What is the advantage of N+1 modular redundancy? N+1 redundancy provides one extra power module beyond the required capacity. This configuration ensures that if a module needs maintenance or replacement, the UPS continues to protect connected loads without interruption, delivering higher availability for critical applications.
• What loads is the 9PXM suitable for? The 9PXM 20kVA/18kW unit is designed for edge data centers, industrial automation, control rooms, and commercial facilities where reliable, scalable power protection is essential. It supports three-phase loads with robust voltage regulation and clean power delivery to sensitive equipment.
• Does it include a cybersecure network card? Yes. The 9PXM model ships with a cybersecure network card to enable encrypted remote monitoring, secure firmware updates, and role-based access management for safer, enterprise-grade management.
• Is the UPS easy to upgrade as loads grow? Absolutely. The modular architecture allows you to add or replace power modules and battery packs, expanding capacity while maintaining uptime. This makes it well-suited for evolving edge environments and expanding data center footprints.
• What connectivity options are available? The system supports hardwired input/output with secure network management. Additional network interfaces or expansion capabilities can be configured through Eaton’s management options in conjunction with the cybersecure card.
• What maintenance considerations are there? Regular self-tests, firmware updates, and battery health checks are recommended. Because the design emphasizes hot-swappable modules, maintenance can often be performed with minimal disruption to protected loads.
