Step 3 Using an 18-gauge wire-stripping tool, strip each of the four wires coming from the DC-input power
source to 0.27 inch (6.6 mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.29 inch (7.4 mm) of
insulation from the wire. Stripping more than the recommended amount of wire can leave exposed wire
from the terminal block plug after installation. (See
Figure 3-13 .)

Step 4 Insert the exposed wire of one of the four DC-input power source wires into the terminal block plug, as
shown in
Figure 3-14 . Make sure that you cannot see any wire lead. Only wire with insulation should
extend from the terminal block.
