Step 2
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 the B feed wires. The switch rear panel identifies the positive
and negative positions for both the A and B feed wires.

Step 3
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 ± 0.02 inch. Do not strip more than
0.29 inch of insulation from the wire. Stripping more than the recommended
amount of wire can leave exposed wire from the terminal block plug after
installation.

Step 4
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. Only wire with
insulation should extend from the terminal block.
