2. Instrukcje bezpieczeństwa
Aby zapewnić bezpieczną obsługę i zapobiec uszkodzeniom, należy przestrzegać następujących środków ostrożności:
- Wejście VoltagWybór: Before connecting the power supply, verify that the input voltage switch (115V/230V) is set to match your local mains voltagmi. Nieprawidłowa objętośćtagWybór ten może spowodować uszkodzenie urządzenia.
- Prawidłowe okablowanie: Ensure all wiring connections are secure and correct. Pay close attention to positive (V+) and negative (V-) DC output terminals and AC input connections (Live, Neutral, Ground).
- Grunt: Always connect the ground terminal to a proper earth ground to prevent electrical shock.
- Zabezpieczenie przed przeciążeniem: Do not exceed the maximum output current of 20A or power of 480W. Overloading can trigger protection mechanisms or damage the unit. For equipment with high peak variations (e.g., motors), select a power supply with at least 2 times the rated power.
- Wentylacja: Ensure adequate ventilation around the power supply. Do not block the cooling fan or ventilation holes. Maintain the operating temperature range of 14℉-140℉ (-10℃-60℃).
- Warunki środowiskowe: Unikaj wystawiania urządzenia na działanie wilgoci, kurzu i ekstremalnych temperatur.
- Profesjonalna instalacja: Installation and wiring should be performed by qualified personnel to prevent electrical hazards.
- Brak części nadających się do samodzielnej naprawy przez użytkownika: Nie otwierać zasilacza casing. There are no user-serviceable parts inside, and opening it voids the warranty.

4. Instrukcje konfiguracji
4.1 Select Input Voltage
Before connecting the power supply to an AC source, it is critical to set the input voltage switch to match your local power grid. The switch is located on the side of the unit. For American and Canadian customers, set it to 115V. For European customers, set it to 230V. Failure to select the correct voltage can result in damage to the power supply and connected equipment.

4.2 Power Supply Check (Initial Test)
After setting the input voltage, perform a quick check:
- Ensure the power supply is not connected to any load devices.
- Plug a power cord (not included) into the AC input port of the power supply.
- Turn on the power switch. Observe the indicator lights. If both the red and green lights are on, the power supply is functioning normally.
- Turn off the switch and unplug the power cord before proceeding to connect your devices.
4.3 Podłączanie urządzenia
Connect your load device(s) to the DC output terminals. The power supply features three positive (V+) terminals and three negative (V-) terminals for connecting multiple devices. Ensure correct polarity to prevent damage to your devices.
- Connect the positive wire from your device to any V+ terminal.
- Connect the negative wire from your device to any V- terminal.
- Sprawdź, czy wszystkie połączenia są dobrze dokręcone i bezpieczne.
