The pin assignment of the two connectorstrips is identical and the connection terminals have numbers foridentifying the connections. You will find the associated figures ineach case at the same place in the circuit diagrams, for exampleeach of the figures quoted in the second place belong to one pos-sible connection method.Measurement ground (–) and the (module) supply voltage areelectrically isolated in the module. NC signifies “No Connection”.The plugs for the A123 module are 5-way plugs with push-inspring technology, i.e. you can insert a solid wire or a fine-stranded wire with a wire-end sleeve directly without screwing(max. 1.5 mm2). With a screwdriver press on the white opener toremove the connection.Fig. 4-79 Pin assignment and plugs for the Q.bloxx module A123.U2, 7 (+)4, 9 (–)1 NC2 AIn 1+3 NC4 AIn 1–5 NC6 NC7 AIn 2+8 NC9 AIn 2–10 NC1 NC2 AIn 3+3 NC4 AIn 3–5 NC6 NC7 AIn 4+8 NC9 AIn 4–10 NC10110 1Plug 1Plug 2I R ext.2, 7 (+)4, 9 (-)
