4. Инсталација и ожичење
УПОЗОРЕЊЕ: Installation must be performed by a qualified electrician in accordance with all local and national electrical codes. Ensure power is disconnected before installation to prevent electric shock.
- Монтирајте волtage protector on a standard DIN rail within a distribution cabinet or control box.
- Connect the incoming Live (L) and Neutral (N) lines from the power source to the 'IN' terminals of the protector.
- Connect the outgoing Live (L) and Neutral (N) lines from the 'OUT' terminals of the protector to the load (e.g., appliances, electrical circuits).
- It is recommended to install a circuit breaker (power switch) before the protector and an air switch (miniature circuit breaker) after the protector for additional safety and circuit isolation.
- Уверите се да су сви прикључци сигурни и правилно изоловани.

5. Operating Instructions and Settings
After successful installation and power-up, the device will display the current voltage and current. You can adjust the protection parameters using the front panel buttons.
5.1. Подешавање параметара
- Press the 'SET' button to enter the parameter setting mode. The first parameter will flash.
- Use the 'Up' (triangle up) and 'Down' (triangle down) buttons to adjust the value of the flashing parameter.
- Press 'SET' again to move to the next parameter.
- Repeat steps 2 and 3 for all parameters: Overvoltage (>U), Undervoltage (<U), Overcurrent (>A), and Reset Time (t).
- After setting all parameters, press and hold the 'SET' button for a few seconds until the display stops flashing to save the settings and exit the setting mode.
5.2. Default and Adjustable Ranges
- Оверволtage Trip Value: Adjustable from 130V to 300V (Default: 270V).
- Ундерволtage Trip Value: Adjustable from 80V to 210V (Default: 170V).
- Overcurrent Trip Value: Adjustable from 1A to 63A (Default: 63A).
- Време ресетовања: Adjustable from 1 second to 999 seconds (Default: 5 seconds).
5.3. Manual ON/OFF
The device can be manually turned ON or OFF using the dedicated ON/OFF button on the front panel.

- Провера везе: Ensure all wiring connections remain tight and secure.
- Тест функционалности: If possible and safe to do so, periodically test the protection functions by simulating an overvoltagе, ундерволtage, or overcurrent condition (e.g., using a test power supply) to confirm the device trips as expected.
ОПРЕЗ: Always disconnect power before performing any maintenance or inspection to avoid electrical hazards.
КСНУМКС. Решавање проблема
If you encounter issues with your JOYELEC Voltage Protector, refer to the following common troubleshooting steps:
| Проблем | Могући узрок | Решење |
|---|---|---|
| Уређај се не укључује. | Нема улазног напајања; неисправно ожичење; унутрашња грешка. | Check power supply and circuit breaker. Verify wiring connections. If problem persists, contact support. |
| Уређај се често искључује. | Волtage/current fluctuations are common; protection settings are too sensitive. | Monitor power quality. Adjust overvoltagе/ундерволtage/overcurrent settings to appropriate levels for your application. |
| Display shows incorrect voltagе/цуррент. | Measurement inaccuracy; sensor issue. | Compare reading with a calibrated multimeter. If significantly different, contact support. |
| Уређај се не ресетује аутоматски. | Reset time setting is too long; fault condition still present. | Check reset time setting. Ensure the voltage/current has returned to normal operating range. |
