Remove the bulk capacitors

Warning

ELECTRIC SHOCK CAN KILL

Let the system release internal voltages before you touch the capacitors. The capacitors can hold a charge for several minutes after the system is set to OFF.

Complete the following procedures:
1. Set the power switch to OFF (O), disconnect the power cord from the power source, and disconnect the gas supply.
2. Remove the plasma power supply cover and handle.
3. Remove the component barrier.

Carefully remove the plenum from the fan casing.

Release the clips in the top 2 corners of the plenum before releasing the bottom 2 clips. See the figure found in this section.

Note:

If necessary, use needle-nose pliers to compress and release the top 2 corner clips before working the bottom 2 clips free from the fan casing.

Notice

DO NOT BREAK THE CLIPS

Be careful not to apply too much pressure to the clips as you disconnect the plenum from the fan.

Remove the 4 capacitor mounting screws from the power board Printed Circuit Board (PCB).

From the opposite side of the power supply (fan side), remove the capacitors by pulling them straight out.
