SOL3-3

11.3.4 Wiring diagram

Note: The diagram shown on the back of the controller housing applies to most of the 
possible system variants. Certain system variant configuration require a different usage 
of   single   relay   outputs.   The   following   table   shows   the   assignment   of   functions   to 
terminals for all system variants.
