The power supply sequence should be set up so that power to
the control unit is turned OFF before the input/output power
supplies.
If the input/output power supplies are turned OFF before the
power to the control unit, the FP0 control unit may detect a
drop in the input level, and malfunction.
Be sure to supply power to a control unit and an expansion
unit from the same power supply, and turn the power ON and
OFF simultaneously for both.
