Connecting the power wires
CAUTION:
•
To protect the power adapter from damages caused by incorrect power cord connections,
identify the input, output, positive (+), and negative (-) marks on the power adapter before
connecting the power wires.
•
Before connecting the power wires, turn off the circuit breaker at the power input end. You can
use a 10 A circuit breaker.
The DC power source equipment in Figure4-2 is for illustration only. Prepare a DC power source
equipment that meets the voltage requirements yourself.
To connect the power wires:
1. Wear an ESD wrist strap and make sure the wrist strap has good skin contact and is reliably
grounded.
2. Connect the positive (yellow) and negative (black) DC output wires of the adapter to the
positive and negative input terminals of the device to which the adapter will supply power,
respectively. Then fasten the wires.
3. Connect the positive (red) and negative (black) DC input wires of the adapter to the positive
and negative poles of the power source equipment, respectively. Then fasten the wires.
4. Verify that the power wires are connected correctly and then turn on the circuit breaker at the
power input end.
