NOTICE!
Risk of damaging the PLC modules!
Overvoltages and short circuits might damage the PLC modules.
–
Make sure that all voltage sources (supply voltage and process supply
voltage) are switched off before you begin with operations on the system.
–
Never connect any voltages or signals to reserved terminals (marked with
