Replacing Assemblies

To remove and replace the power supply

To remove and replace the power supply

1Using previous procedures, remove the following assemblies:

•Handle

•Rear Feet

•Cover

•Disk Drive

W A R N I N G

Hazardous voltages exist on the power supply. To avoid electrical shock, disconnect the power from the instrument before performing the following procedures. After disconnecting the power, wait at least three minutes for the capacitors to discharge before servicing the instrument.

2Lift the PCB locking pins out of the chassis.

3Slide the power supply out far enough to reach the power supply cables, then disconnect them from the power supply.

4Slide the power supply the rest of the way out the side of the instrument.

5 Reverse this procedure to install the power supply.

Check that the following assemblies are properly installed before installing the power supply:

•Monitor

•Front Panel

•Switch Actuator

•Main Circuit Board

To remove and replace the Main Circuit board

1Using previous procedures, remove the following assemblies:

•Handle

•Rear Panel

•Cover

•Disk Drive

•Power Supply

2Disconnect the GPIB and RS-232C cables from the Main Circuit board.

3 Disconnect the front panel cable from the Main Circuit board.

4 Disconnect the monitor board cable from the Main Circuit board. 5 Slide the board out the rear of the instrument.

6 Reverse this procedure to install the Main Circuit board.

Check that the following assemblies are properly installed before installing the Main Circuit board:

•Monitor

•Front Panel

•Switch Actuator
