Step 7
Align the two captive screws with the screw holes. Using a ratcheting torque screwdriver, torque each
screw to 7 lbf-in (112 ozf-in).
Step 8
Connect the input power as described in the
“Wiring the DC-Input Power Source”
section.
Wiring the DC-Input Power Source
Step 1
Using a wire-stripping tool, strip each of the four wires coming from the DC-input power source to the
appropriate length for either the round eyelet or the fork-type terminals.
Step 2
Using a Panduit crimping tool, crimp the terminals to the 16-gauge DC-power input wires.
Step 3
Connect the DC-input power terminals to the terminal blocks as shown in
. Make sure to
match the polarity (negative to negative, positive to positive) when connecting the wires to the terminal
blocks.

Step 4
Torque all terminal block screws to 5 lbf-in (80 ozf-in).
Step 5
Replace the terminal block plastic safety cover. Torque the safety-cover screw to 10 lbf-in (160 ozf-in).
Step 6
Move the DC-power source circuit-breaker handles to the ON position.
