Step 1
Flip the circuit breaker actuator on the PFU installed in the bay labeled Power Filter Unit 1 to the OFF position. If the
circuit breaker on the PFU is equipped with a locking clip, lock the circuit breaker in place by moving the breaker's
locking clip to the right until the clip's inside tang is recessed in the breaker's actuator opening.
Step 2
Remove the plastic cover from the power terminals with a #2 Phillips head screw driver.
Step 3
Use a 9/16-inch nut driver or socket wrench to remove the nuts and the lock-washers from each of the four terminals.
Step 4
Connect 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 with two of the four washers and two of the four nuts that you removed in step
3. The nuts should be torqued to 50 in-lb. (5.65 N-m).
Step 5
Connect 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.
