How to use

Place the Eaton 3P900UI on a flat, stable surface with adequate ventilation and connect critical loads to the AC outlets. Plug the UPS into a grounded mains outlet and allow the internal battery to charge for several hours before relying on battery backup. Use the USB ports where supported to connect to a computer for basic monitoring or to charge peripherals.

Replace the internal battery according to the manufacturer’s maintenance schedule or when runtime degrades.
