Installation 2

Step 2. Install the HV control PCA and cables

1 Turn off the system power and remove the system power cord.

The power cord should be kept intact if the vacuum control switch box is

used. The switch box is intended to keep the vacuum on while a CE works

on the electronics. The switch box is for CE use only.

2 Remove the CDS cover, top, side, front, and the Aux Module cover.

3 Disconnect the ribbon cable that connects the valve PCA to the

Vcap/Vchamber power supply. Then disconnect the Vcap and Vchamber

cable from the power supply.

4 Place the MM HV power supply PCA in the slot between the valve PCA and

the Vcap/Vchamber. Secure the board by pressing it down into its slot and

then attach it with two screws.

5 Connect the short gray cable from valve PCA to the multimode HV power

supply.
