CAUTION!
Risk of damaging the processor module!
– Never short-circuit or overload the outputs.
– Never connect inductive loads without an external suppression against
voltage peaks due to inductive kickback.
– Never connect voltages > 240 V. All outputs must be fed from the same
phase.
– Use an external 5 A fast protection fuse for the outputs.
