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, as shown in Figure C-5.

Step 3
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, as shown in
Figure C-5
.

Step 4
Using a 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), as shown in
Figure C-6
. 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.
