out before it can be put into service.
INFORMATION

attached correctly. The red LED should not light up if gentle pressure is applied to the
edges of the safety light grid.

Check that the safety distance complies with the requirements stated in Maintaining the
safety distance.
}
Check that the area between the safety light grid and the hazardous machine compon-
ent is inaccessible from all sides.
