Do not pull on the wire when disconnecting the spade lug connectors from the battery’s terminals
— pull only on the connector. Pulling on the connector using a side-to-side tugging motion may
ease removal. A pair of needle nose pliers may supply a better grip on the connector — do not
pull with too tight of a grip in order not to damage the connector.
4.2.8. Installing the battery
Ensure that the unit is powered off and is disconnected from the power cord before attempting to
install the battery.
1) Place the battery into its housing in the orientation noted during removal. Make sure that the
wires are clear from being pinched by the battery.
2) Plug the spade lug connectors into the appropriate terminals on the battery.
3) Position the cover plate with the screws lined up above the flanges behind the paper holder,
then lower the back of the cover. Make sure that the wires are clear from being pinched by the
cover plate.
4) With the cover plate in position, slide the tabs into their slots in the housing and tighten the two
screws to secure the plate to the chassis.
5) In case a fold of paper from the paper roll has been pinched by the battery cover plate, loosen
the two screws on the battery cover plate, clear the paper from under the cover plate, and tighten
the two screws again.
6) Replace the printer cover.
4.2.9. Removing the power supply
The power supply consists of the following components:
•
primary power supply area
•
secondary power supply area
•
battery
The primary power supply area houses the high voltage AC and the secondary power supply
area houses the low voltage AC and DC power. The battery provides a backup power source in
case of AC power failure. The primary power supply area is behind the battery compartment.
The primary power supply housing and secondary power supply housing are welded together and
completely enclosed with protective covers.
Before attempting this procedure, ensure that all external cables have been disconnected from
the unit, and the AccuVote-OS has been powered off.
1) Prepare the 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) Remove the cover using the procedure previously described in Removing the cover . Position
the chassis with its front panel facing you.
3) You need to disconnect the following cables:
•
the three-wire power supply cable connecting the power supply with the card reader
•
the four-wire power supply cable connecting the power supply with the CPU board
•
the two static ground cables connecting the power supply to the CPU board
•
the card reader ribbon cable connecting the card reader to the CPU board
