Preparing the Cables for a 300 W DC Power Supply
You need a crimping tool to attach the terminals to the power and ground cables.
To prepare the cable wires, follow these steps:
1. On each cable wire, strip 6 mm (0.25 inch) of insulation from one end.
2. Insert the end of one power cable wire all the way into the barrel of a spade terminal and crimp the
terminal securely to the wire.

3. Repeat step Preparing the Cables for a 300 W DC Power Supply on page 334 for the other power
cable wire.
4. Insert the end of the stripped ground wire (green or green and yellow) all the way into the barrel of
the ring terminal and crimp the terminal securely to the wire.
