Maintenance 6

Enabling Front or Rear Binding Posts

6.Turn over the 5725A so that the top is facing up.

7.Remove the high voltage heat sink assembly as described under “Accessing the High Voltage Output Transistors", steps 2 through 4.

8.Remove the two screws that secure the Interconnect assembly and pop the assembly free of the two bosses.

6-15. Enabling Front or Rear Binding Posts

The 5725A comes from the factory configured for front or rear current output as requested by the purchaser when the system was ordered. Only one output location can be enabled at a time. You can reconfigure the output location by opening the chassis, detaching a cable and tying it away, and attaching another cable to a jack on the Current Amplifier assembly.

Warning

To avoid electrical shock, proceed only after completing the initial access procedure, which removes line power and checks for high voltage on the power supply.

Proceed as follows to change the current output location:

1.Perform the Initial Access Procedure.

2.Remove the five retaining screws on the Current Amplifier assembly. Lift the current amplifier assembly by pulling on the plastic wire-tie loops, and place the assembly in the service position.

3.Refer to Figure 6-7, and locate J222 on the Current Amplifier assembly.

4.Perform step 5 to change from front to rear, or perform step 6 to change from rear to front.

5.To enable the rear binding posts and disable the front, remove the cable that goes to the front binding posts from J222, and plug the cable that goes to the rear binding posts into J222.

6.To enable the front binding posts and disable the rear, remove the cable that goes to the rear binding posts from J222, and plug the cable that goes to the front binding posts into J222.

Use a non-conductive plastic wire tie to secure the unused cable to the right side ventilation slots.
