How to Install Eaton 9PXM

• Plan the installation in a climate-controlled rack environment with adequate airflow and clearance for maintenance access and battery module replacement. Verify the 208-240V supply is available and that the rack space meets the unit’s 14U height and weight specifications.
• Mount the UPS in the 14U rack using the provided rails and hardware. Secure the chassis to the rack, ensuring it is level and stable to prevent vibration or movement during operation.
• Connect the hardwired input cables from your building power distribution to the UPS input terminals, following local electrical codes and Eaton installation guidelines. Do not power the unit until all connections are verified for correctness.
• Attach the hardwired output connections to your critical loads or distribution panel, ensuring proper labeling and separation from non-critical circuits. Route cables to minimize interference and maintain serviceability.
• Install and connect any modular battery packs as required. Allow initial charging to complete before placing the system under full load, and monitor the battery status via the included network card to track charge levels and health.
• Insert the Cybersecure Network Card into the designated slot and connect it to your secure network. Configure remote management access, user permissions, and firmware update schedules to maintain cyber resilience.
• Power up the UPS and run an automated self-test sequence. Confirm normal operation, observe voltage stability on the output, and verify alarm and notification settings on your monitoring system.
