Looks like you just hook the incoming LINES to the the L1 and L2 Terminals and the COM and COM2 Terminals. The pump and SWG would then be hooked up to the NO and NO2 Terminals.
The wire color does not matter ... ASSUMING ... they are the 2 lines of a 230V circuit.
Right above the diagram it says that the trippers need to be out to turn it on.
Your SWG is wired for 230V like the pump right?
