Wiring
STRA-07 has been constructed to be as compact as
possible. Therefore, the controller’s communication input
is not galvanically separated from the supply voltage.
This means that it is important to keep G and G0 in order,
as well as the communication input’s A and B.
All units that share the same transformer and
communication loop must use the same transformer-
pole for G (terminal 10) and G0 (terminal 11). On the
communication loop the A-terminal (terminal 42) should
only be connected to another A-terminal and the B-
terminal (terminal 43) to another B-terminal. Otherwise,
there is great danger of short-circuit with damaged
components as a result.
