power cable.
2. Remove the cabinet cover of the 3080 by loosening the seven (7)
screws securing the cover (the screws do not have to be
removed)
3. Disconnect the long black HV controller connector by pulling it
up and then loosen the two screws on the sides of the HV
controller body from the mounting bracket as shown in
Figure 6-11 and Figure 6-13.
