Accessories with accessory board (AA5)
Accessories with accessory board (AA5) are connected
to the control module’s terminal block AA100-X9:8–10.

If several accessories are to be connected, connect the
first accessory board directly to the terminal block in
SMO S40. Other accessory boards are connected to the
first in series.
Because there can be different connections for accessor-
ies with accessory board (AA5), you should always read
the instructions in the manual for the accessory that is
to be installed.
