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 front panel of the switch identifies the positive and negative positions for both the A and B feed
wires (See
Figure C-7
.)

Step 4
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.

Step 5
Insert the exposed wire of one of the four DC-input power source wires into the terminal block plug, as
shown in
Figure C-9
. Make sure that you cannot see any wire lead. Only wire
with
insulation
should
extend from the terminal block.
