5. התקנה (הגדרה)

Follow these steps for proper installation of the EDR-120-24 power supply.

5.1 הרכבה

1. The EDR-120-24 is designed for DIN rail mounting on TS-35/7.5 or TS-35/15 rails.
2. Ensure sufficient clearance for air circulation. A minimum of 5mm left and right, 40mm above, and 20mm below the power supply is recommended for optimal cooling.
3. To mount, hook the top edge of the power supply onto the DIN rail, then push the bottom edge firmly until it clicks into place.

5.2 חיווט

All connections are made via screw terminal blocks. Refer to the Terminal Pin Assignment tables in Section 4.

1. Input Wiring (TB1): Connect the AC mains (L, N) or DC input (+, -) to the corresponding terminals. Ensure the Frame Ground (FG) terminal is properly connected to earth ground. The input voltagטווח e הוא 90-264VAC או 127-370VDC.
2. Output Wiring (TB2): Connect your load to the DC OUTPUT +V and -V terminals.
3. סוג חוט: Use copper wire only, rated for a minimum of 75℃.
4. עֲנָק: Ensure terminal screws are tightened to the specified torque (Input: 6.5 Lb-in, Output: 5.5 Lb-in) to prevent loose connections.

איור 4: דוגמהample wiring diagrams for different input configurations. Always refer to the product label for specific terminal markings.

6. תפעול

Once installed and wired correctly, the EDR-120-24 is ready for operation.

• הפעלה: Apply the specified AC or DC input voltage.
• מחוון DC תקין: A green LED labeled "DC OK" will illuminate when the output voltage נמצא בטווח המקובל.
• פלט כרךtage התאמה: התפוקה כרךtage can be finely adjusted using the "+V ADJ" potentiometer located on the front panel. Use a small screwdriver to turn the potentiometer clockwise to increase voltage or counter-clockwise to decrease it.

7. תחזוקה

The EDR-120-24 is designed for long-term reliability with minimal maintenance. However, periodic checks are recommended.

• ניקוי: Keep the unit clean and free from dust and debris, especially around ventilation openings, to ensure proper air convection cooling. Use a soft, dry cloth for cleaning.
• בדיקות חיבור: Periodically inspect all wiring connections for tightness and signs of corrosion. Re-tighten screws if necessary after disconnecting power.
• ניטור סביבתי: ודא שסביבת ההפעלה נשארת במסגרת גבולות הטמפרטורה והלחות שצוינו.

8. פתרון תקלות

If the power supply is not functioning as expected, consider the following common issues:

• No Output / DC OK LED Off:
  • Check input power connections and voltage.
  • Verify that the input fuse (if external) is intact.
  • Check for short circuits or overloads on the output. Disconnect the load and re-test.
  • Ensure the ambient temperature is within the operating range.
• פעולה לסירוגין:
  • בדוק אם יש חיבורי חיווט רופפים.
  • Verify that the load current does not exceed the rated output current (5A). Overload protection may be activating.
  • Ensure adequate ventilation to prevent over-temperature shutdown.
• עוצמת פלט שגויהtage:
  • Adjust the "+V ADJ" potentiometer.
  • ודא את כרך הקלטtage יציב ובטווח שצוין.

If problems persist after checking these points, contact qualified service personnel or the manufacturer.
