How to use

Install the UPS on a stable, flat surface in a ventilated area away from direct heat and moisture. Connect essential equipment to the UPS output outlets and plug the UPS into a grounded mains supply to charge the internal battery. During normal operation the unit provides voltage regulation; when mains power fails, the UPS switches to battery power to maintain connected loads for the estimated runtime. Follow the manufacturer’s user manual for battery commissioning, firmware or software setup, and recommended safety procedures for maintenance and battery replacement.

Recommendations

Position the UPS so vents are unobstructed and periodically verify battery charge and health. Prioritize mission-critical devices on the UPS outlets to maximize the available runtime, and schedule automated shutdowns for nonessential systems to conserve battery during extended outages.
