Data Expansion Head Enhanced – Reassembly and Fitting
To Reassemble and fit the Data Expansion Head Enhanced
1. Insert the connector board into the expansion head housing.
2. Secure the connector board with the four screws previously removed.
3. Insert the rubber frame.
4. Insert the 40-pin flex from the connector board to the Expansion board, ensuring that the top
latch is firmly closed.
5. Snap the Expansion board into the expansion head housing.
6. Connect the 12 line flex to the Terminal, top small connector.
7. Connect the 40 line flex to the Terminal, bottom large connector.
8. Close the top latch after flex insertion.
9. Push the expansion head housing onto the terminal until all the diecast tabs snap firmly into
place.
NOTE:
For correct orientation, the contacts of both flexes should face the PCB. Connect the
flex from the Data Expansion Head Enhanced to the top small connector in the
terminal with the 'dot' or 'O' facing upwards away from the terminal; make sure the
'dot' or 'O' aligns with the 'O' on the terminal.
NOTE:
• The Expansion Head has a protection grade of IP54. To maintain IP54 sealing when
connecting a RS232 data cable, make sure to use a IP54 specified cable
(example: ROLINE AT-Modem cable ST-BU 1.8m order no. 11.01.4518).
• The flex is not designed for continuous insertion, replace after several uses.
