注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding to avoid electric shock; maintain sufficient ventilation around the device for heat dissipation (avoid blocking air vents)

2 Operation:

3 Follow the derating curves for ambient temperature and input voltage; for output voltage below 12V and ambient temperature between -15°C to -30°C, derate output current to 90% of rated value

4 Use only compatible modules (NMS-240/NMD-240) designed for NMP1K2 model; do not exceed the maximum total output power of 1200W

5 Ensure the shorting connector is assembled for global ON/OFF control if required; set global/local ON/OFF switches correctly to avoid unintended power cuts

6 When using current sharing function, connect CS pins of parallel modules properly and ensure output voltage difference between modules is less than 0.2V

7 Do not use the output current programming (PC) function when modules are in parallel

8 Use remote sense (±S) correctly to compensate for voltage drop on load wiring (up to 0.5V)

9 Maintenance:

10 Disconnect power supply before performing any maintenance or inspection; do not open the device case without professional training

11 Regularly check for loose connections, dust accumulation, and signs of damage (e.g., burnt marks, swollen capacitors)

12 Keep the device away from dust, moisture, corrosive gases, and extreme temperatures to prolong service life

13 Safety: Avoid touching live parts during operation; use appropriate personal protective equipment (insulated gloves, goggles) when handling the device; comply with local electrical safety regulations
