4.2 Start-Up Procedure

  1. Make sure that the jumper at JP2 (Enable High Control) is covered to connect VIN to pin 1 of JP3. Also make sure JP3 (Enable Control) pin 2 and 3 are covered to shunt EN to GND to disable the output.
  2. Apply appropriate input voltage to VIN (J1-1) or TP1 and GND (J1-2) or TP8. Note that the board cannot support hot plug-in. The input lines must be connected between J1 and an external power source first before turning on the power source.
  3. Move the jumper at JP3 (Enable Control) from pin 2 and 3 (EN and OFF) to pin 2 and 1 (EN and ON) and make sure JP2 pin 1 and pin 2 are covered. Then, the output can be enabled.
  4. Apply the loading to VOUT (J2-2) or TP4 and GND (J2-1) or TP10.
