6. Návod k obsluze
Turning the UPS On/Off
- Zapnout: Press and hold the power button for approximately 2 seconds until you hear a beep and the indicators light up.
- Vypnout: Press and hold the power button for approximately 2 seconds until you hear a beep and the indicators turn off.
LED indikátory
The front panel features LED indicators that provide information about the UPS status:
- Zelená LED: Indicates AC mode (normal operation, power supplied from mains).
- Žlutá LED: Indicates battery mode (power supplied from batteries during an outagE).
- Červená LED: Indikuje poruchu nebo přetížení.
Automatický svtage Regulace (AVR)
The UPS automatically regulates incoming voltage fluctuations. If the input voltage is too high or too low, the AVR function will adjust it to a safe level without switching to battery power, protecting your connected devices.
Provoz v režimu baterie
Během výkonu outage, the UPS will automatically switch to battery mode, providing power to connected devices. The yellow LED will illuminate, and the UPS will emit an audible alarm. The runtime depends on the connected load.
Obrázek 6.1: Battery runtime chart for the NJOY Keen UPS. At 25% load, runtime is approximately 13 minutes. At 50% load, runtime is approximately 4 minutes. At 75% load, runtime is approximately 1 minute. At 100% load, runtime is less than 1 minute.
When the battery level is low, the UPS will emit a more frequent alarm. It is recommended to save your work and shut down connected equipment gracefully during this period.
Funkce automatického restartu
After a complete power outage and subsequent restoration of AC power, the UPS will automatically restart and power on connected devices, provided the battery has sufficient charge.
7. Údržba
- Péče o baterie: To maximize battery life, keep the UPS connected to an AC outlet at all times. If the UPS is stored for an extended period, recharge it every three months for at least 8 hours.
- Čištění: Disconnect the UPS from the AC power and all connected devices before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid or aerosol cleaners.
- Větrání: Regularly check that the ventilation openings are clear of dust and obstructions to ensure proper cooling.
