5. ການຕິດຕັ້ງ (Setup)

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

5.1 ການຕິດຕັ້ງ

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 ສາຍໄຟ

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