A.1 Powering Up the CDA 7
DANGER:
If the CDA 7 is in need of repair, only qualified personnel familiar with
safety procedures for electrical equipment and the CDA 7 should access
components inside the unit.
Perform these steps to power on the CDA 7 after it has been powered off by the AC
power switch.
1. Make sure all operator panel switches (channel director and disk director) are
in the disable position.
2. Lift the EPO switch on the rear door to the up (|) position.
3. Lift the AC power switch on the rear door to the up (|) position. The CDA 7
begins its IML procedure. This procedure takes several minutes to perform.
NOTE:
The power controls are inoperative unless the Emergency Power Off (EPO)
switch on the rear door is in its enabled (up, | position). The EPO switch when
turned off (down, O position) disables all power to CDA 7 including the backup
battery systems.
