The battery piggyback SMPBBAT is fitted into the socket BU3 on the
SMART-BASE. It is important that the piggyback is inserted in the correct
way. The figure below illustrates this procedure.

Once fitted on the board, the battery should be on the right hand side of the
SMPBBAT piggyback. If the battery needs to be replaced, it must only be
done with a replacement SMPBBAT piggyback, the order number of which
is shown in the Ordering Information section of this manual.
The temperature on the battery must not exceed +70 C, due to the risk of
battery damage! For SMART I/O modules with extended temperature ranges
of up to 85 C, a special lithium battery must be fitted to the SMPBBAT.
