WARNINGS
Static electricity can damage sensitive components.
Observe safe handling precautions for static-sensitive components.
Use proper grounding procedures/codes.
If the scanner is installed in a high voltage environment and a fault or installation error
occurs, high voltage may be present on any lead or terminal.
To access the connectors, remove the enclosure cover and unscrew the two captive screws that fasten
the display module into the enclosure. Disconnect the ribbon cable and remove the display module. RS-
485 serial connections are made to a removable terminal block on the back of the display module. Power
and signal connections are made to a barrier terminal connector in the base of the enclosure. Grounding
connections are made to the two ground screws provided on the base – one internal and one external.
Use proper grounding techniques and observe all local and national electric codes.
