Connecting Power
Step 5 Identify the positive and negative feed positions for the terminal block connection. The wiring sequence
is positive to positive and negative to negative for both the A and B feed wires.
Figure 2-27 Positive and Negative Positions
The rear panel of the power supply unit identifies the positive and negative positions for both the A and
B feed wires. See Figure 2-27.
Figure 2-28 Stripping the DC-Input Power Source Wire
Step 6 Using an 18 gauge wire-stripping tool, strip each of the four wires coming from the DC-input power
source to 0.25 inch (6.3 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.
Warning
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.
