注意事项 PRECAUTIONS

1 Installation:

2 Use recommended screws (M4 for front-end, M3.5 for modules) and torque (12Kgf-cm for AC terminal,10Kgf-cm for DC terminal); avoid over-penetration of screws

3 Ensure proper grounding of FG terminal to prevent electric shock

4 Operation:

5 Global ON/OFF: Assemble the shorting connector (RC1 to GND-P) if not using global control; otherwise, no output will be present

6 Local ON/OFF: For NMS-240 modules, open RC2-GND to turn on, short to turn off; for NMD-240, use RC2/GND1 (V1) and RC3/GND2 (V2)

7 Remote sense: Use twisted pairs for +S/-S lines to minimize noise; do not exceed 0.5V compensation limit

8 Parallel operation (NMS-240 only):

9 Connect CS pins of all modules together; ensure output voltage difference <0.2V between modules

10 Total current should not exceed sum of rated currents of modules; max 6 modules for NMP1K2

11 Do not use PC (current programming) function when modules are in parallel

12 Remote control must turn all parallel modules on/off simultaneously

13 Derating:

14 For output voltage <12V and ambient temp -15~-30°C, derate output current to90% of rated

15 Follow derating curves for ambient temperature and input voltage to avoid overheating

16 Maintenance:

17 Disconnect AC/DC input power before opening the unit or replacing modules

18 Use only Meanwell-approved accessories and modules to ensure safety and performance

19 Environmental:

20 Avoid operating in condensing humidity or corrosive environments

21 Ensure adequate airflow for cooling (follow air flow direction as per specs)
