5. Настройка
Follow these steps for initial setup of your UPS:
- Распакаванне: Асцярожна выміце бесперабойнік з упакоўкі. Праверце на наяўнасць пашкоджанняў пры дастаўцы.
- Размяшчэнне: Place the UPS on a flat, stable surface in a well-ventilated area, away from direct sunlight, heat, and moisture. Ensure adequate space around the unit for airflow.
- Першапачатковая зарадка: Connect the UPS to a standard grounded AC power outlet. Allow the UPS to charge for at least 6-8 hours before connecting any devices to ensure optimal battery performance. The UPS will charge whether it is turned on or off.
- Падключэнне прылад: After initial charging, connect your devices (e.g., WiFi router, desktop PC, monitor) to the output sockets on the rear panel of the UPS. Ensure the total power consumption of connected devices does not exceed the UPS's capacity (600VA / 360W).
- Уключэнне: Press the power button on the front panel to turn on the UPS. The LED indicators will illuminate to show its status.
6. Інструкцыя па эксплуатацыі
