Preparing the Cables for a 750 W DC Power Supply
Before you begin
You will need two cable wires for each installed DC power supply: one input cable and a grounding cable. As a best practice, each cable should have differently colored insulation, as described in
Required Tools and Materials for Installing a 750 W DC Power Supply
.
About this task
To prepare the cable wires, follow these steps:
Procedure
Strip 6 mm (0.25 inch) of insulation from one end on each cable wire if necessary.
Repeat step
1
for the other cable wire.
