4. Insert the MPU Controller board into the case and carefully guide the connector end of the board until it mates
with the connector at the back of the case. Only when the connectors are mated should additional force be
applied to seat the board.
5. If an Ethernet board is installed, connect the free end of the Ethernet cable, from inside the case, to the Ethernet
connector J4 on the board. See Section 11.5.6 as necessary.

After replacing an I/O Expander board in a controller whose configuration includes an
AINU function block: assemble the controller, apply power, ENTER configuration and
STORE the SEN TYPE parameter. This must be done even if the SEN TYPE displays
the desired type. This will ensure that the function block loads the correct calibration
from the new Expander board. If desired, a FIELD CAL can then be performed.
