4. 설정 및 설치

4.1 장착

Ensure the main power is OFF before mounting.
Mount the MDR-40-24 onto a standard TS-35/7.5 or TS-35/15 DIN rail.
Ensure sufficient clearance (at least 10mm on top and bottom, 5mm on sides) for proper ventilation.
The unit should be mounted vertically to allow for optimal heat dissipation through convection.

4.2 배선 연결

Refer to the markings on the unit for correct terminal connections. Use appropriate wire gauges for the current rating.

Input Terminals (AC):
- L: Live AC input
- N: Neutral AC input
- : 보호 접지
Output Terminals (DC):
- +V: Positive DC output (24V)
- -다섯: Negative DC output (0V / Ground)
DC OK 릴레이 연락처:
- Provides a signal indicating the DC output status. Refer to the product datasheet for detailed relay specifications.

메모: Ensure all connections are secure and tightened to the specified torque of 5 Lb-in to prevent loose connections and potential hazards.

5. 사용 설명서

5.1 전원 켜기

After completing all wiring connections, switch on the main AC power supply.
The "DC OK" LED indicator on the front panel should illuminate, indicating normal operation.

5.2 출력 볼륨tage 조정

The MDR-40-24 features a potentiometer labeled "+V ADJ" on the front panel for fine-tuning the output voltage.

Using a small screwdriver, carefully turn the potentiometer clockwise to increase the output voltage 또는 시계 반대 방향으로 돌리면 감소합니다.
출력 볼륨 모니터링tage with a multimeter to ensure it is within the desired range and does not exceed the maximum safe operating voltage for your connected devices.

주의: 출력 볼륨을 조정하지 마십시오tage beyond the recommended range specified in the product datasheet to avoid damaging the power supply or connected equipment.

6. 유지관리

The MEAN WELL MDR-40-24 is designed for reliable operation and requires minimal maintenance.

청소: 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 and disconnected before cleaning.
통풍: Ensure that the ventilation openings are not obstructed by dust or debris. Clear any blockages to maintain proper airflow.
점검: 배선 연결부가 단단히 고정되었는지, 마모 또는 손상 흔적이 있는지 정기적으로 점검하십시오.
