How to use
Place the tower UPS on a stable, ventilated surface away from direct heat and moisture. Connect the UPS to mains power and allow it to charge for the recommended recharge time before relying on battery backup. Plug critical equipment into the battery-backed outlets and non-critical loads into surge-only outlets if available. Use the USB 2.0 connection to link the UPS to a computer running compatible power management software to enable automatic, orderly shutdown when battery runtime becomes low. Periodically inspect the unit, keep vents unobstructed and follow manufacturer maintenance guidelines for battery care.
Usage recommendations
For consistent performance, avoid loading the UPS beyond its 900 W rated output and spread high-startup-load devices across separate power sources. Maintain the unit in a temperature-controlled environment and perform battery replacement as recommended by the manufacturer to ensure reliable backup operation.
