1. Loosen the terminal screws for +, -, and GND.

2. Slide the wires one at a time (green = GND, red = +, black = -) into the square openings in

the bottom of the terminal block.

3. Tighten the terminal screws so that they crimp the wires.

4. Use an ohmmeter to verify that power leads are not shorted to GND.

5. Connect the + and - wires to the power source.

6. Insert the terminal block into the DC power receptacle at the front of the 9145ELB.
