5. Орнотуу жана орнотуу

The NDR-120-24 is designed for easy installation on standard DIN rails (TS-35/7.5 or TS-35/15).

5.1 Монтаждоо

To mount the power supply, align the top clip of the unit with the top edge of the DIN rail. Push the bottom of the unit firmly towards the rail until it clicks into place. Ensure the unit is securely fastened.

For optimal cooling, ensure there is sufficient clearance around the unit, especially above and below, to allow for free air convection.

5.2 Зымдарды туташтыруу

Connect the input and output wires to the appropriate terminals. Refer to the labels on the unit for correct polarity and connection points. Use copper wire only, with a minimum temperature rating of 75°C.

• Input Terminals (L, N, ⌂): Connect the AC line (L), neutral (N), and protective earth (⌂) wires.
• Output Terminals (-V, +V): Connect the DC load to the negative (-V) and positive (+V) output terminals.
• Терминалдык момент: Ensure all terminal screws are tightened to 6.5 Lb-in (0.74 Nm) to ensure secure electrical contact and prevent loosening due to vibration.
