Ensure that the jumper at JP2 (Enable High
Control) is covered to connect VIN to pin 1 of JP3. Also ensure JP3 (Enable
Control) pin 2 and 3 are covered to shunt EN to GND to disable the output.
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 external power source first before turning on the power
source.
Move the jumper at JP3 (Enable Control) from pin
2 and 3 (EN and OFF) to pin 2 and 1 (EN and ON). Make sure JP3 pin 1 and pin 2 are
covered, then the output can be enabled.
Apply the loading to VOUT (J2-2) or TP4 and GND (J2-1) or TP10.
