5. Instalazioa (Konfigurazioa)

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

5.1 Muntaketa

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 Kableatua

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 voltagSormena 90-264 VAC edo 127-370 VDC da.
2. Output Wiring (TB2): Connect your load to the DC OUTPUT +V and -V terminals.
3. Hari mota: Use copper wire only, rated for a minimum of 75℃.
4. Torque: Ensure terminal screws are tightened to the specified torque (Input: 6.5 Lb-in, Output: 5.5 Lb-in) to prevent loose connections.

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

6. Funtzionamendua

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

• Piztu: Apply the specified AC or DC input voltage.
• DC ondo dagoen adierazlea: "DC OK" etiketa duen LED berde bat piztuko da irteerako bolumena iristen denean.tage tarte onargarriaren barruan dago.
• Irteera boltage Doikuntza: Irteerako bolumenatage 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. Mantentzea

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

• Garbiketa: 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.
• Konexioaren egiaztapenak: Periodically inspect all wiring connections for tightness and signs of corrosion. Re-tighten screws if necessary after disconnecting power.
• Ingurumenaren jarraipena: Ziurtatu funtzionamendu-ingurunea zehaztutako tenperatura eta hezetasun mugen barruan dagoela.

8. Arazoak

Energia-iturriak espero bezala funtzionatzen ez badu, kontuan hartu ohiko arazo hauek:

• 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.
• Etengabeko funtzionamendua:
  • Egiaztatu kable bidezko konexio solteak.
  • 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.
• Irteerako bolumen okerratage:
  • Adjust the "+V ADJ" potentiometer.
  • Egiaztatu sarrerako bolumenatage egonkorra da eta zehaztutako tartearen barruan dago.

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