Please turn off the AC power and remove the conditions causing fan-lock. If there are no observable causes for fan-lock, please remove the unit from your system and send back to our local distributor or MEAN WELL for repair.
Page 13 5.8.2 Single Output Module ON/OFF ◎The NMS-240 modules can be turned ON/OFF individually by using the “ON/OFF” function. ◎Figure 5-5 shows RC2 (CN81 PIN3) and GND (CN81 PIN1 or 2) connection diagram. Connection Status Output Module Status Open (SW OFF) Short (SW ON) NMS-240...
Page 14: Output Module Remote Sense
Output Module Remote Sense(NMS-240 only) ◎ Built-in remote sense circuit that is able to compensate voltage drop up to 0.5V. ◎ When using this function, the sensing wires should either be twisted or shielded to prevent external noise interference (refer to Figure 5-7). ◎...
Page 15: Dc-Ok Signal And Led Indicator
5 11 DC-OK Signal and LED Indicator ◎ DC-OK signal and LED indicator are both used to indicate operation status of the output module. When the output module is operating properly, the DC-OK signal is "HIGH" (4.5~5.5V) and the LED indicator is lit, otherwise, the logics are reversed. ◎...
Page 16: Parallel Operation
Parallel Operation(NMS-240 only) ◎ Up to 4 (NMP650) or 6 (NMP1K2) modules of the same output voltage rating may be connected in parallel. ◎ Before making the parallel connection, adjust the voltage of each module individually to the desired voltage, and ensure the difference in voltage is less than 0.2V.
Page 17: Assembly
Assembly Assembly Procedures STEP 1: ◎ For first time assembly, please remove the Front-End from packaging and proceed to STEP 2. ◎ If the NMP unit has been configured and assembled previously, please turn off the unit and remove all input/ output connections. ◎...
Page 18 Mylar film Mylar film Note : Mylar films need to fold over the modules STEP 4: ◎ Once all modules have been installed or reconfigured, place the top cover back and secure with screws as shown below. While securing the top cover, ensure all modules are held secure by the notches and screws. Please set the electric screw driver's torque setting to 6kgf-cm.
Page 19 STEP 6: ◎ Connect AC power to the NMP unit and test each module to ensure proper operation. The green LED indicator on module should light up. ◎ Measure the output voltage of each module and make sure it is within the specified output voltage tolerance range. If the load requires a different voltage that is within the specified voltage adjustment range, adjust the voltage by turning the SVR as shown below.
Page 20: Assembly Example
◎ In parallel operation, CS and GND pins of CN81 of all modules need to be connected in parallel. MEAN WELL offers connection accessories for 2 units (NMS-240-P2), 3 units (NMS-240-P3), 4 units (NMS-240-P4), 5 units (NMS-240-P5), and 6 units (NMS-240-P6).
