To access the system board inside the enclosure, you can either open the back cover of the
enclosure or remove the unit from the enclosure with its front plate.
To open the back cover, first remove the four screws on the sides of the cover. If necessary,
also loosen the four screws on one of the end plates of the enclosure.
It is also possible to access the system board from the front side. To remove the front plate,
first remove the 6 screws holding the plastic front cover. Remove the cover and remove the 6
screws on the sides of the front plate. You can now lift the metal front plate of the system with
electricall parts attached. Disconnecting the communication flat cable, power cable and
keyboard cable connectors allows removing the unit for service.
2.3 CONTROL UNIT ELECTRICAL CONNECTIONS
Fig. 2.3.1 shows the MC300 control unit system board. Additionally, a daughter board
DPI02410 is used in panel/flush mount versions for connections. In the MC300 with enclosure
the connections go through D-15 connectors via a connector card at the end plate of the
enclosure. These boards both connect to the S2 connector on the system board (MCU1).
