4.2.1. Removing the cover
Ensure that all external cables are disconnected from the unit and the unit is powered off before
removing the cover.
1) Position the unit on a work surface that provides access to the sides, front and rear of the unit.
Using a Phillips (+) screwdriver, remove the four screws on the sides of the unit and the one
screw from the rear of the unit illustrated above.
2) With the front panel facing you, raise the AccuVote-OS cover and place it on its back
immediately behind the AccuVote-OS. Ensure that there is enough slack in the card reader's
ribbon cable and the three-wire power supply cable to prevent damage to connections. The card
reader’s ribbon cable and the three-wire power supply cable should not be detached at this time.
4.2.2. Replacing the cover
Ensure that all external cables are disconnected from the unit and the unit is powered off before
replacing the cover.
1) Place the unit cover face down, behind the back of the base of the AccuVote-OS.
2) Check that all internal cables, including the card reader’s ribbon cable and the three-wire
power supply cable, are connected. Ensure that the internal cables are clear from being pinched
or damaged by the installation of the unit cover.
3) Lower the unit cover so that the lip on the rear and sides of the cover will sit inside the edge of
the unit chassis.
4) Replace the four screws on the sides of the unit and the one screw at the rear of the unit.
Refer to Figure 5-1.
5) Reconnect all external cables that were disconnected before removing the AccuVote-OS
cover.
4.2.3. Removing the card reader assembly
Ensure that all external cables are disconnected from the unit and the unit is powered off before
removing the card reader assembly.
