Connecting the Protective Ground and Power
Step 3 Measure two strands of twisted-pair copper wire (18-to-20 AWG) long enough to connect to the DC
power source.
Step 4 Using an 18-gauge wire-stripping tool, strip each of the two twisted pair wires coming from each
DC-input power source to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.27 inch
(6.8 mm) of insulation from the wire. Stripping more than the recommended amount of wire can leave
exposed wire from the power connector after installation.
