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
---). Reserved terminals may carry internal voltages.
NOTICE!
Risk of malfunctions in the plant!
A ground fault, e. g. caused by a damaged cable insulation, can bridge switches
accidentally.
Use sink inputs when possible or make sure that, in case of error, there will be
no risks to persons or plant.
