POWER WAVE CURRENT TRANSDUCER

REMOVAL AND REPLACEMENT (CONTINUED)

REMOVAL PROCEDURE

1. Remove input power to the Power Wave

455/R.

2. Using the 3/8” nut driver, remove the case

top and sides and the control box cover.

3. Perform the Capacitor Discharge proce-

dure.

4. Using the 3/8” socket wrench or nut driver,

remove the three screws along the bottom
case front. See Figure F.26.

5. Using the 3/8” socket wrench, remove the

four screws that hold the case front to the
machine.

6. Label all leads to all output terminals. Using

the 5/16” wrench and the 3/4” wrench,
remove all leads from the three output termi-
nals. See the Wiring Diagram.

7. Cut any necessary cable ties. Then careful-

ly swing the front panel aside.

8. Remove the insulating tape from the heavy

lead bolted connection. See Figure F.26.
Using the 9/16” wrenches, remove the bolt,
lock washer and nut.
