Using a 12- or 14-gauge wire-stripping tool, strip each of the four wires coming
from the DC-input power source to 0.27 inch (6.86 mm) ± 0.05 inch (1.27 mm).
(See Figure 2-23.) Do not strip more than 0.29 inches (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.
Figure 2-23 Stripping the DC-Input Power-Source Wire
0.25 in. (6.3 mm) ± 0.02 in. (0.5 mm)
Insert the exposed wire of one of the four DC-input power source wires into the
terminal block plug. Make sure that you cannot see any wire lead. (See
Figure 2-24.) Only wire with insulation should extend from the terminal block
plug.
An exposed wire lead from a DC-input power source can conduct harmful levels
of electricity. Be sure that no exposed portion of the DC-input power source
wire extends from the terminal block plug.
