2. Make certain the FlexBus connector (1) is pushed all the way to the
left to connect with the neighboring terminal base/adapter.
You cannot install the module unless the connector is fully
extended.
3. Make sure the pins on the bottom of the module are straight so they
will align properly with the connector in the terminal base unit.
4. Position the module (8) with its alignment bar (7) aligned with the
groove (6) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit.
The module is seated when the latching mechanism (2) is locked into
