3. Инструкции за безбедност
- Инсталацијата мора да ја изврши квалификуван персонал во согласност со локалните електрични кодови и прописи.
- Пред да извршите каква било инсталација, поврзување или одржување, осигурајте се дека главното напојување е исклучено.
- Не го изложувајте уредот на влага, вода или екстремни температури.
- Не го отворајте casing од напојувањето. Внатре нема делови што може да ги сервисира корисникот.
- Потврдете го влезниот волуменtage and frequency match the specifications of the power supply before connection.
4. Поставување и инсталација
4.1 Монтирање
- Select a suitable location within an electrical cabinet or distribution board that allows for proper ventilation.
- Mount the FERMAX 4825 power supply onto a standard DIN rail. Ensure it is securely fastened.
4.2 Приклучоци за жици
Refer to Figure 1 for terminal locations.
- Влезна моќност (AC): Connect the main AC power supply to the terminals labeled N (Neutral) and L (Line). Ensure proper polarity. The input range is 100-240V AC, 50-60 Hz.
- Приклучок за земја: Connect the protective earth ground to the terminal marked with the ground symbol.
- Output Power (DC): Connect the DUOX Plus equipment requiring 24V DC power to the terminals labeled + и - under "OUTPUT". The output is 24V DC, 2.5A.
- Power Bus / Prev Bus: Connect the DUOX Plus system bus lines to the "POWER BUS" and "PREV BUS" terminals as per your specific DUOX Plus system diagram. These terminals are typically used for data and power distribution within the intercom system.
Important: Double-check all wiring connections before applying power to prevent damage to the unit or connected equipment.
5. Упатства за работа
5.1 Вклучување
- After ensuring all connections are secure and correct, switch on the main AC power supply to the unit.
- The "ON" LED indicator on the front panel should illuminate, indicating that the power supply is active and providing output voltage.
5.2 Индикатори за статус
- НА ЛЕР: Illuminates when the power supply is receiving input power and operating normally.
- OVERLOAD LED: Illuminates if the output current exceeds the rated 2.5A, or if a short circuit is detected on the output.
6. Одржување
The FERMAX 4825 power supply is designed for reliable, long-term operation with minimal maintenance. Follow these guidelines:
- Чистење: Periodically clean the exterior of the unit with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure the unit is powered off before cleaning.
- Вентилација: Ensure that the ventilation openings are not obstructed to allow for proper air circulation and cooling.
- Проверки за поврзување: Occasionally check all wiring connections to ensure they remain tight and secure.
7 Смена на проблеми
- No "ON" LED illumination:
- Check if the main AC power supply is connected and active.
- Verify the input wiring (N, L) is correct and secure.
- "OVERLOAD" LED illuminates:
- This indicates an overcurrent condition or a short circuit on the 24V DC output or connected DUOX Plus bus lines.
- Immediately disconnect the main AC power supply to the unit.
- Inspect all connected DUOX Plus equipment and wiring for short circuits or excessive load.
- After resolving the issue, wait approximately one minute before reconnecting the main AC power supply to allow the electronic fuse to reset.
- If the problem persists, the connected equipment may be drawing too much current, or the power supply itself may be faulty.
- No Voltage / Sin Tensión / Nicht Spannung:
- This label on the unit indicates the absence of voltage. If the "ON" LED is off and there is no output, refer to the "No 'ON' LED illumination" troubleshooting steps.
