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 service
engineer works on the electronics. The switch box is for service engineer
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.

the Vcap/Vchamber power supply. Secure the board by pressing it down
into its slot and then attach it with two screws.
5 Connect the short gray cable from the valve PCA to the multimode HV
power supply.
