NOTICE!
Risk of damaging the I/O module!
The outputs are not protected against short circuit and overload.
– 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 supplied from the
same phase.
– Use an external 5 A fast protection fuse for the outputs.
