CONNECTING COMMUNICATION
ECS 40/ECS 41 contains an accessory board (AA5) that
connects directly to the main product’s input board
(terminal block AA3-X4).
For F1345 on terminal block X6 or on terminal block
AA101-X10 F1345 2.0/F1355.
If more accessories are to be connected, or are already
installed, the boards are connected 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.
