Step 3 Turn off the power at the circuit breakers for the portions of the DC grid power that you are connecting to
and verify that all of the LEDs on the DC grid power supplies are off.

a) If the unconnected end of each power cable is not stripped of its insulation for the last 0.75 inches (19

b) Attach the negative cables to the negative terminals of a DC power source, and attach the positive cables
to the positive terminals of the same power source.
