4.2. Ground connection

PSEN op4F/H-s safety light curtain units are preset for easy ground

connection. A special compartment, positioned onto caps and

marked with the special symbol shown in Figure 21, allows

connection with ground cable by means of an additional screw

coming with the equipment.

Fig. 21

Ground connection configuration is the most common and

guarantees the best immunity against electromagnetic disturbances.

PSEN op4F/H-s can function even without ground connection.

This condition has to be carefully evaluated according to the EMC

disturbance immunity and necessary insulation class considering the

plant or entire system where the light curtain is installed.
