Installing the Replacement PFU
Step 5
Use a Phillips #2 screw driver to remove the plastic cover from the power terminals.
Step 6 Use a 9/16-inch nut driver or socket wrench to remove the nut and the lock-washer on the PFU from each of the four
terminals.
Step 7
Fasten the lug attached to the power return cable to the PFU:
a) Insert the lug over the two terminals labeled RTN. These are the two top terminals on the PFU.
b) Secure the lug to the RTN terminals using two of the four washers and two of the four nuts that were removed in
step 3. The nuts on the PFU should be torqued to 50 in-lb. (5.65 N-m).
Step 8 Fasten the lug attached to the power feed cable to the PFU:
a) Insert the lug over the two terminals labeled -VDC. These are the two bottom terminals on the PFU.
b) Secure the lug to the -VDC terminals with the remaining two washers and nuts you removed in step 7. The nuts on
the PFU should be torqued to 50 in-lb. (5.65 N-m).
To avoid the risk of fire, take proper precautions to ensure that the power feed and return lugs are not touching.
