4.2 Start-Up Procedure

  1. Ensure that the jumper at JP2 (Enable control) pins 2 and 3 are covered to shunt EN to GND, disabling the output.
  2. Apply appropriate input voltage to VIN (J1-1) or TP1 and GND (J1-2) or TP6. The input lines should be connected between J1 and external power source first before turning on the power source.
  3. Move the jumper at JP2 (Enable control) from pins 2 and 3 (EN and OFF), to pins 1 and 2 (EN and ON) and make JP1 pin 1 and pin 2 are covered, then the output can be enabled.
  4. Apply the loading to Vout (J2-1) or TP4 and GND (J2-2) or TP10.
