注意事项 PRECAUTIONS

1 Ensure the shorting connector (RC1 to GND-P) is properly assembled; otherwise, the unit will not output power

2 Parallel module operation guidelines:

3 Connect CS pins of all parallel modules together

4 Ensure output voltage difference between modules is less than 0.2V

5 Total output current should not exceed the sum of rated currents of parallel modules and the total power limit (1200W for NMP1K2)

6 Use short, large-diameter wiring for parallel connections to minimize voltage drop

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

8 Remote sense: Use twisted pairs for +S/-S lines to reduce electromagnetic interference; this function compensates up to 0.5V voltage drop

9 Temperature derating: Follow the derating curve—for example, when output voltage <12V and ambient temperature is between -15°C and -30°C, derate the output current to 90% of the rated value

10 Global/local ON/OFF control: Set the switches correctly (open for ON, short for OFF for local control; refer to the function manual for details)

11 Auxiliary power limits: Do not exceed the maximum load current for +5V-AUX-P (2A for NMP1K2) and Vcc2 (10mA for modules)

12 Over-temperature monitoring: Use the T-Alarm signal to detect overheating; the signal is high (4.5~5.5V) when the internal temperature exceeds the limit

13 Wiring: Use appropriate wire gauge (20~26AWG for control lines) and torque for terminals (e.g., M3.5 screws for output terminals with maximum torque of 10Kgf-cm)

14 Storage and operation conditions: Operate within -30°C to +70°C (with derating) and store within -40°C to +85°C; avoid condensing humidity

15 Voltage/current programming: Follow the specified voltage ranges for PV (voltage programming) and PC (current programming) pins to prevent damage to modules
