注意事项 PRECAUTIONS

1 Installation precautions: Use M4 screws with 7~10 Kgf-cm torque for mounting; ensure proper grounding; follow air flow direction for heat dissipation

2 Operation guidelines:

3 Global ON/OFF: Short RC1 (CN32-PIN6) to GND-P (CN32-PIN3) if not using global control; open for OFF, short for ON

4 Local ON/OFF: For NMS-240 modules, open RC2 (CN81-PIN3) to GND (PIN1/2) to turn on; for NMD-240 modules, open RC2/RC3 to respective GNDs

5 Remote sense: Connect +S/-S pins to load terminals to compensate voltage drop; max compensation 0.5V

6 Programming functions: Use PV pin for output voltage adjustment (refer to specs) and PC pin for current adjustment; do not use PC function in parallel mode

7 Parallel operation notes:

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

9 Total output current ≤ (rated current per module × number of modules); total power ≤1200W

10 Max 6 modules in parallel; use short, large-diameter wiring for parallel connections

11 Environmental considerations:

12 Operating temperature range: -30~+70℃; derate output current at high temperatures (refer to derating curve)

13 For output voltage <12V and ambient temp -15~-30℃, derate current to 90% of rated value

14 Safety warnings: Disconnect AC/DC input before maintenance; avoid touching live parts; comply with relevant safety regulations for specific applications

15 Maintenance: Regularly check for loose connections; keep the device clean and free of dust to ensure heat dissipation
