8. Replace the smallest cable restraint on the far right, and tighten the captive screw to

hold the power cables for INPUT 0, INPUT 1, INPUT 3, and INPUT 4 in place.

9. Route the positive (+) DC source power cables for RTN 0, RTN 1, RTN 3, and RTN 4

over the largest cable restraint on the left. The left cable restraint is marked as follows

from top to bottom RTN 0, RTN 1, RTN 3, and RTN 4.

NOTE: You must route the cables as marked to be able to replace the

clear plastic cover over the terminal studs.

Attach the negative (–) DC source power cable lugs to the RTN terminals on the left:

RTN 0, RTN 1, RTN 3, and RTN 4. Secure the cable lugs to the terminal studs, first with

the washers, then with the nuts. Using a 7/16-in. (11 mm) nut driver, tighten the nuts.

Apply between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each nut.

10. Replace the left cable restraint, and tighten the captive screw to hold the power cables

for RTN 0, RTN 1, RTN 3, and RTN 4 in place.
