PROCEDURE

1.Remove the input power to the V350-PRO.

2.Using a 5/16” nut driver remove the case wrap- around cover.

3.Perform the Input Filter Capacitor Discharge Procedure detailed earlier in this section.

CAUTION

Observe static precautions detailed in PC Board

Troubleshooting Procedures at the beginning of

this section. Failure to do so can result in perma-

nent damage to equipment.

4.Locate the main switch board and all associat- ed plug and lead connections. See figure F.23. See Wiring Diagram.

5.Using a 5/16” and 3/8” nut driver remove the input lead shield from the area at the bottom of the main switch board.

6.Using a 7/16” socket, remove leads 201, 202, 203, 204, 205, 206, 207, 208, 209 from the switch board. Note lead terminals locations and washer positions upon removal.

7.Locate and disconnect the three harness plugs associated with the main switch board. Plugs #J20, #J21, #J22. See Figure F.23.

8.Locate the eight capacitor terminals and remove the nuts using a 7/16” socket or nut driver. Note the position of the washers behind each nut for replacement.
