2. Instruccions de seguretat
Read all instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or damage to the device.
- Personal qualificat: La instal·lació i el manteniment només els ha de dur a terme personal qualificat.
- Desconnexió d'alimentació: Always disconnect the AC input power before performing any installation, wiring, or maintenance.
- Connexió a terra adequada: Ensure the device is properly grounded to prevent electric shock.
- Ventilació: Do not obstruct ventilation openings. Ensure adequate airflow around the unit to prevent overheating.
- Condicions ambientals: Do not operate the device in environments exceeding its specified temperature and humidity ranges. Avoid exposure to moisture or corrosive substances.
- Sobrecàrrega de sortida: Do not exceed the rated output power or current.
3. Configuració i instal·lació
Follow these steps for proper installation of the HDR-15-12 power supply.
- Muntatge: Mount the power supply onto a standard TS-35/7.5 or TS-35/15 DIN rail. Ensure the unit is securely fastened. The unit should be mounted vertically to allow for proper heat dissipation.
- Cablejat d'entrada: Connect the AC input wires to the designated terminals (L, N, and FG) on the power supply. Use appropriate wire gauges for the input current. The input voltage range is 85~264 VAC or 120~370 VDC.
- Cablejat de sortida: Connect the DC output wires to the designated terminals (+V and -V). Ensure correct polarity. The output is 12V DC.
- Ajustament de terminals: Ensure all terminal screws are securely tightened to prevent loose connections and potential hazards.
- Verificació: Abans d'aplicar l'alimentació, comproveu dues vegades que totes les connexions del cablejat siguin correctes i segures.
