WARNING!
Risk of death by electric shock!
Hazardous voltages can be present at the terminals of the module.
Make sure that all voltage sources (supply voltage and process supply voltage)
are switched off before you begin with operations on the system.
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 fuse to protect the outputs.
