注意事项 PRECAUTIONS

1 Before powering on, confirm that the input voltage matches the product's rated range (AC90~264V or DC120~370VDC) to avoid damage

2 Use only compatible NMS-240 (single output) or NMD-240 (dual output) modules from MEAN WELL; blank slots must be covered with BLANK-NMS240 accessories to ensure safety and dustproof performance

3 When using the remote sense function, correctly connect the +S/-S pins to the load terminals to compensate for voltage drop on the wiring (max 0.5V)

4 For parallel operation of modules: Connect the CS pins of all modules, ensure the output voltage difference between modules is less than 0.2V, total power does not exceed 1200W (NMP1K2), and use short, large-diameter wires for parallel connections

5 Follow derating guidelines: For output voltage <12V and ambient temperature between -15°C and -30°C, derate the output current to 90% of the rated value; refer to the product's derating curve for other conditions

6 Do not exceed the maximum load current of auxiliary power outputs (5V/2A for front-end,5V/10mA per module) to prevent damage to auxiliary circuits

7 Ensure proper grounding of the product to meet safety and EMC requirements; use a grounding wire with sufficient cross-sectional area

8 Avoid operating the product in environments with excessive dust, moisture (relative humidity >90% non-condensing), or corrosive gases; maintain good ventilation around the product for heat dissipation

9 Before performing maintenance or module replacement, disconnect the power supply and wait at least 5 minutes for capacitors to discharge completely to avoid electric shock

10 Use only original or MEAN WELL-approved accessories for parallel/series connections or other extensions; unauthorized accessories may cause safety hazards or performance issues
