Ensure that the J3 (Enable control) pins 1 and 2 are shorted to shunt EN to GND, disabling the output.
Apply appropriate input voltage to VIN (J1-2) or
TP2 and GND (J1-1) or TP4. Note that the board cannot support hot plug-in.
Connect the input lines between J1 and external power source first before
turning on the power source.
Disconnect J3 (Enable control) pins 1 and 2 (EN
and L). Ensure that pins 2 and 3 (EN and H) are shorted, then the output can be
enabled.
Apply the loading to VOUT (J2-1) or TP7 and GND (J2-2) or TP10.
