b.
Unscrew the two nuts in each of the four terminal slots inside the terminal box.
c.
Remove a lug from each terminal (total of four lugs).
d.
For each of the four power cables, carefully crimp a lug on the end of the cable. Be sure not to
deform the lug or cable in a way that prevents you from fitting the lug back into one of the terminal
slots. Also, ensure that each lug is securely fastened to the cable by attempting to pull the cable out
of the lug.
e.
Attach each cable lug to a terminal by placing it on two terminal posts and fasten it with two nuts
tightened to 40 in-lb (4.5 N·m).
Note
For all your power connections, if you are using cables with two different colors, use one color
cable for all positive circuits and use the other color for all negative circuits.
f.
Replace the safety cover on the terminal box and fasten it with three screws.
