How to use

Place the UPS on a stable, level surface with adequate ventilation and keep it away from direct heat sources and liquids. Connect the critical devices to the two AC outlets, then plug the UPS into a grounded AC mains outlet. Turn on the UPS using the power button and confirm operational status on the LCD. The unit will provide automatic voltage regulation during fluctuations and switch to battery power during mains outages. Monitor battery condition and load level via the LCD and, when possible, perform orderly shutdown of connected equipment if runtime is expected to be insufficient.

Recommendations

To ensure reliable performance, avoid continuously loading the UPS near its maximum rated output. Periodically check the battery status on the LCD and schedule battery replacement according to usage and age. For extended backup needs or multiple devices, consider a UPS with higher capacity or additional outlets. Use the UPS in a temperature-controlled environment and allow at least several hours of charging after initial installation before relying on full backup capability.
