Replacing Assemblies

Using Torx T20 screwdriver, remove the 4 screws that
secure the 600 watt power supply to the chassis.

Slide the power supply toward the front panel and lift it
out of the frame while holding the line filter cable for the
lower power supply out of the way.

Reverse this procedure to replace the 600 watt power
supply.

Secondary power supply

The secondary power supply is 175 watts and may look
different than the one shown here.

Perform the procedures:

•

“To prepare the instrument for disassembly”
