4) Grip the three-wire power supply cable connector located below the motor on the card reader
and remove from the card reader.
5) Grip the four-wire power supply cable connector next to the printer assembly and remove from
the CPU board.
6) Grip the static ground cable connectors located between the printer assembly and the four-wire
power supply header on the right hand side of the CPU board and remove from the CPU board.
7) Place two fingers on both lock eject levers on either side of the card reader ribbon cable
connector located on the CPU board and push outwards in order to release the cable from the
CPU board.
Once you have removed the cables, place the unit cover to one side.
8) Position the chassis face down on the protective material with the front panel facing you. Make
sure that the LCD display and the printer are protected and will not be damaged.
9) Using a Phillips (+) screwdriver, remove the eight screws securing the power supply housing
assembly onto the unit chassis.
10) Lift the chassis up in order to remove from the power supply housing assembly and set it
aside, face up, ensuring that no power supply wires remain tangled in the chassis.
4.2.10. Installing
the power supply
Before attempting this procedure, ensure that all external cables have been disconnected, and
the AccuVote-OS has been powered off.
1) Prepare your work surface with a thick, soft, non-abrasive layer of material such as foam, in an
area large enough for the chassis. This precaution is to prevent any damage to the LCD, printer,
or connectors.
2) Place the power supply housing assembly face down on your work surface, with the battery
compartment facing towards you.
3) With the chassis positioned face down, and its front panel facing you, gently lower it onto the
power supply housing assembly, making sure that the LCD and printer will not be damaged.
4) Position the chassis so that the chassis mounting holes for the power supply housing assembly
are properly aligned with the mounting holes in the power supply.
5) Using a Phillips (+) screwdriver, replace the eight screws to secure the housing assembly to
the chassis. The screws may be replaced in any order.
6) Position the unit chassis face up, with the front panel facing you.
7) Position the unit cover face down, behind the unit chassis.
8) Plug the three-wire power supply connector into the male connector below the motor on the
card reader.
9) Plug the four-wire power supply connector into the male connector next to the printer assembly
on the CPU board.
10) Press the ballot reader serial cable connector into the header located in the right hand corner
of the CPU board.
The connector should be oriented so that the ribbon cable travels towards the back of the
chassis, rather than the front of the chassis. The locking eject levers on both sides of the header
should snap into place once the connector has been installed.
11) Reconnect the two static ground connectors located on the CPU board.
12) Replace the unit cover using the procedure previously described in
