Use a torque-limiting Torx T-15 screwdriver and pliers for this procedure.
Refer to the exploded view diagram. (See page 8-8.)
Removal.
1. Remove the power button and rear case. (See page 6-10, Rear Case.)
2. Disconnect the following wires:
The ground wire on the power supply module from the chassis ground lug.
The display adapter power supply cable from P2.
The power supply cable on the Main board at J101. Press down on the
latch while pulling up on the cable.
3. Remove the five screws that connect the power supply module to the chassis
and lift the module from the internal assembly.
Installation.
1. Align and place the power supply module into the internal assembly.
2. Install the two longer screws with thread lock into the IEC connector
mounting holes.
3. Install the three shorter screws through the power supply and into the chassis.
4. Connect the following wire and cables: (See Figure 6-3.)
The ground wire on the power supply module to the chassis ground lug.
You may need to use pliers to secure the wire in place.
The display adapter power supply cable at P2.
The power supply cable to the Main board at J101. Twist the cable to keep
it from contacting the boards and chassis.
NOTE.
Wind up the power supply cable until it is tight; loops are okay. This
keeps the cable bundle together.
5. Assemble the oscilloscope by performing the installation procedure for each
module that was removed.
